The following is a high-level view of changes made to Crazy Eddie's GUI System for each release.

<b>Release 0.7.6</b>
- Bug Fix: Backported the TinyXML API version check and related code conditionals from default (cmake) branch to here (autotools).
- Bug Fix: Make ScrolledContainer not issue the content changed notification when in the destruction phase.  This fixes issues in clients of ScrolledContainer that respond to this notification.  Via patch from Erik Ogenvik.
- Bug Fix: include of cstddef header was missing for ptrdiff_t useage.  see: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=3&t=5546
- Bug Fix: remove incorrect instances of 'size_t' from lua package files.  See: http://www.cegui.org.uk/mantis/view.php?id=441
- Bug Fix: Ensure MCL keeps selection in single-select mode(s).
- Bug Fix: Issue where empty variable would break configure script.
- Bug Fix: Python detection should firstly not specify an exact version, and secondly should look for 2.7 as a possible version.
- Bug Fix: make.bat file for regenerating the lua binding on Windows had the wrong output path
- Bug Fix: Apply patch from ianstangoe to save/restore viewport and projection matrix in Ogre renderer.  See: http://www.cegui.org.uk/mantis/view.php?id=430
- Bug Fix: Some include guards were incorrect.
- Bug Fix: Remove offset from label area in Vanilla/Button that was throwing off centred text.  This issue is what originated this ticked: http://www.cegui.org.uk/mantis/view.php?id=426
- Bug Fix: Resolve issue where content attached to a FrameWindow that is initially in the 'rolled up' state does not immediately display when the FrameWindow is subsequently unrolled.  http://www.cegui.org.uk/mantis/view.php?id=409
- Bug Fix: Add bounds checking to ensure clipping regions will always be valid as scissor rects (all sides >=0).  Insurance against future like this one: http://www.cegui.org.uk/mantis/view.php?id=403
- Bug Fix: resolve issue where a totally clipped Window attached to a parent with a RenderingWindow surface would generate an invalid clipping rect for it's GeometryBuffer.  This is the likely source of the issues in this ticket: http://www.cegui.org.uk/mantis/view.php?id=403
- Bug Fix: Ensure GeometryBuffer clip rects are initialised to something when creating those objects.
- Bug Fix: issue where '0' was tested as a default mouse cursor value instead of MouseCursorImageLLDefaultMouseCursor (-1)
- Bug Fix: resolve issue I introduced which could set mouse image to address -1 and cause a seg fault.
- Bug Fix: Resolve issue where FrameWindow::isTitleBarEnabled and
- Bug Fix: FrameWindow::isCloseButtonEnabled used inherited state thus causing incorrect image and incorrect inner rect areas to be used when FrameWindow was disabled.  http://www.cegui.org.uk/mantis/view.php?id=411
- Bug Fix: Resolve issue where initial call of MouseCursor::constrainPosition would access uninitialised d_position member variable.  http://www.cegui.org.uk/mantis/view.php?id=401
- Bug Fix: Detect __HAIKU__ as a *nix variant.  Thanks to michaelvoliveira for a patch.  http://www.cegui.org.uk/mantis/view.php?id=417
- Bug Fix: Issue where Window::setMouseCursor did not update the cursor image immediately if the cursor was already within the window's area.  http://www.cegui.org.uk/mantis/view.php?id=412
- Bug Fix: Issue where we would try to (re)create Tooltip as part of system destruction when WindowManager is in locked state.  http://www.cegui.org.uk/mantis/view.php?id=423
- Bug Fix: ScrolledContainer should pass mouse events back to it's parent in order that things like mouse scroll wheel works.
- Bug Fix: Divisoin by zero / NaN issue with slider where the thumb would end up never getting a correct position.  Thanks to Erik Hjortsberg.
- Bug Fix: Resolve issue where a destroyed window could leave references to it's GeometryBuffer in some RenderingSurface queue.
- Bug Fix: errors in the VanillaWindows.layout example file.
- Bug Fix: Issues of deleting a class instance that was only forward referenced.
- Bug Fix: The config option to exclude PCRE did not exclude a PCRE specific header.

- Modified: Move to system default compiler and system default OS X SDK in order that ppl are not forced into having specific versions of the dev tools installed (and by 'people', I mean me :-p)

- Added: Functions that allow people to do useful things in WindowRenderer implementations (and other places).
- Added: InventoryDemo.
- Added: Null animation name support
- Added: isAnimationPresent
- Added: Eol extension + it's settings so Windows developers don't pollute the repo with CR LF
- Added: RadioButton to Vanilla, via patches from Ident.
- Added: Checkbox to Vanilla skin, via patches from Ident. 
- Added: Window::getZIndex, Window::isInFront and Window::isBehind functions to enable client code to discover z-ordering of windows.

<b>Release 0.7.5</b>
- Added: Initial version of the officially supported Python extension modules:
    - PyCEGUI - Support for the core CEGUI library.
    - PyCEGUIOpenGLRenderer - Support for the OpenGL based renderer.
    - PyCEGUIOgreRenderer - Support for the Ogre based renderer.
    - PyCEGUINullRenderer - Support for the Null renderer.

- Modified: Grimmigbeisser's patch improving the menu system - automatically opening/closing popups after certain time, closing all nested popups when their parent is closed and PopupOffset (closes http://www.cegui.org.uk/mantis/view.php?id=408)

- Documentation: Kulik is a team member now!


<b>Release 0.7.4</b>
This version was issued as an 'emergency release' to fix the following:
- Bug Fix: CEGUI::Editbox masked text issue.  See: http://www.cegui.org.uk/mantis/view.php?id=399


<b>Release 0.7.3</b>
- Bug Fix: Ensure return value from injectMouseButtonDown is consistent in all cases.  See: http://www.cegui.org.uk/mantis/view.php?id=397
- Bug Fix: Ensure IrrlichtResourceProvider correctly detects when a file does not open successfully (as opposed to just checking that it exists).  See: http://www.cegui.org.uk/mantis/view.php?id=395
- Bug Fix: resolve infinite recursion issue involving Tooltip::positionSelf.  Solution is not all that elegant, but it does work and does not break other things which could happen by 'tuning' where we call positionSelf.  See: http://www.cegui.org.uk/mantis/view.php?id=394
- Bug Fix: Resolve issues where user can delete the system default Tooltip and leave a dangling pointer.  Tooltip is now recreated whenever it's needed after having been deleted. See: http://www.cegui.org.uk/mantis/view.php?id=391
- Bug Fix: remove default param to resolve ambiguous function call. http://www.cegui.org.uk/mantis/view.php?id=386.
- Bug Fix: Do not have String::iterator subclass String::const_iterator, since it prevents common iterator behaviours (because it was never possible to receive an object that behaved like a non-const iterator).  See: http://www.cegui.org.uk/mantis/view.php?id=384.
- Bug Fix: Blending issues on OpenGL renderer when using the WGL pbuffer support.
- Bug Fix: Blend mode issue in OpenGL renderer when using Apple pbuffer based targets.
- Bug Fix: Blend mode issue in OpenGL renderer when using GLX pbuffer based targets.
- Bug Fix: Manually set viewport dimensions in the OgreRenderer could be lost if no internal viewport existed at the point when the dimensions were set.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=10&t=5141
- Bug Fix: Resolved OgreRenderer issues relating to when no render target / view port is set and Renderer::beginRendering gets called.  See: http://www.cegui.org.uk/mantis/view.php?id=367 and http://www.cegui.org.uk/mantis/view.php?id=379
- Bug Fix: The layout container tolua++ package files were missing from the source distributions.  See: http://www.cegui.org.uk/mantis/view.php?id=388
- Bug Fix: CEGUI::ScriptFunctor was not exported from CEGUIBase.dll in Win32.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=2&t=5109

- Modified: Fire Combobox::EventListSelectionAccepted /after/ activating the editbox part of the control, which should allow handlers to pop-up and activate other windows.
- Modified: Changed default setting in lua module target in Xcode so the release build is not built with the 'safe' mode enabled.
- Modified: Apply Kulik's animation system patch that allows skipping of the next frame when things are lagging after an anim (re)start.
- Modified: Applied Kulik's layout container patch to address some nested container issues.  NB: Part of this change makes Window::update function virtual.

- Added: Facility to specify left, right or centred formatting for the Editbox.  See: http://www.cegui.org.uk/mantis/view.php?id=277
- Added: configure option to allow the control over whether the lua module is built in 'safe' mode in non-debug builds.
- Added: ImageCodec module based on stb_image.c (from http://nothings.org/).  Thanks to Tobias Schlegel.  See: http://www.cegui.org.uk/mantis/view.php?id=375.  NB: Still to test on MSVC and add targets in Xcode.
- Added: Facility to clone a window.  Via Kulik's patch.  For: http://www.cegui.org.uk/mantis/view.php?id=352


<b>Release 0.7.2</b>
- Bug Fix: Resolve issue where auto generated buttons for TabControl could cause CEGUI::AlreadyExistsException to be thrown due to using only part of the content window name.  Issue resolved by using the entire content window name.  See: http://www.cegui.org.uk/mantis/view.php?id=383.
- Bug Fix: Resolved infinite recursion bug in String::iterator::operator+.  Thanks to Kulik.
- Bug Fix: Removed unnecessary Win32 DLL import/export control macro from CEGUI::RefCounted template class.  Thanks to Kulik.
- Bug Fix: ConstBaseIterator::operator!= was completely incorrect.  Thanks to Kulik.
- Bug Fix: Resolve issue where tooltip window area was not always correctly pixel aligned. 
- Bug Fix: Resolve issue where slider thumb offset from the thumb track area would be incorrectly applied twice.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=3&t=5009
- Bug Fix: Address the issue relating to 'incorrect' firing of EventMouseEnters and EventMouseLeaves by adding EventMouseEntersArea and EventMouseLeavesArea events that exhibit the more expected behaviour.  See: http://www.cegui.org.uk/mantis/view.php?id=231
- Bug Fix: event propagation in Window would terminate when the parent was modal, not when 'this' was modal.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=10&t=5066
- Bug Fix: RenderedString on Window was not invalidated when using appendText and insertText functions.  See: http://www.cegui.org.uk/mantis/view.php?id=382.
- Bug Fix: ProgressBar WindowRenderer did not ensure clipper used for progress rendering was pixel aligned, which could cause 'texel-twinkling' issues.  See: http://www.cegui.org.uk/mantis/view.php?id=372 and http://www.cegui.org.uk/phpBB2/viewtopic.php?f=3&t=4931.
- Bug Fix: Parameter names in FrameWindow header were switched.  See: http://www.cegui.org.uk/mantis/view.php?id=378.
- Bug Fix: Issue where String::replace using an iterator range for the replacement substring was checking the wrong iterators for the 'erase' case.  See: http://www.cegui.org.uk/mantis/view.php?id=377
- Bug Fix: seg / hang caused by off by one argument validation check in String::erase.  See: http://www.cegui.org.uk/mantis/view.php?id=376.
- Bug Fix: Fix issues relating to RenderingWindow surfaces having thier clipping region set up incorrectly in some circumstances.
- Bug Fix: Typo in CEGUI::FreeTypeFont.  See: http://www.cegui.org.uk/mantis/view.php?id=371
- Bug Fix: OgreTexture::saveToMemory did not work all the time.
- Bug Fix: We no longer need to save linker aggro because we don't link directly to CEGUIXercesParser any more, so instead it's better not to link everything to xerces-c :-p
- Bug Fix: Help and status strings in configure that relate to the ImageCodec modules.
- Bug Fix: Ensure main libs var is not contaminated with image libs, otherwise we end up linking everything to freeimage or some such thing.
- Bug Fix: Resolve issues with build flag setup / contamination which lead to all modules being linked against the GL and X11 libs.
- Bug Fix: Resolve some issues regarding external tolua++ libs, including searching for alternate names and ensuring we include dependent libs when checking. See: http://www.cegui.org.uk/mantis/view.php?id=368
- Bug Fix: Ensure ceguitolua++bin links to the Lua libs correctly. See: http://www.cegui.org.uk/mantis/view.php?id=368
- Bug Fix: the generated configure script would continue without pkg-config being installed.  See: http://www.cegui.org.uk/mantis/view.php?id=370
- Bug Fix: TaharezLook/Button's 'DisabledImage' was not being used where it should have been.
- Bug Fix: Bug in String regarding calculating number of UTF-32 code points represented by a UTF-8 encoded buffer where a malformed / truncated UTF-8 buffer and can result in infinite loop condition.  Many thanks to gring.
- Bug Fix: Bug in String regarding calculating number of UTF-32 code points represented by a UTF-8 encoded buffer containing 4 byte encoded sequences causing overrun of input buffer.  Many thanks to myself :-p
- Bug Fix: Remove reference to non-existent font.
- Bug Fix: Bug where rendering sureface was not invalidated when a child window is removed.
- Bug Fix: Only report that a RenderedStringTextComponent can be split if it really, really, really can ;)  Fixes hang in wordwrap code when string is a single space.
- Bug Fix: fixed copy/paste error in HelperFunctions.pkg file.  See: http://www.cegui.org.uk/mantis/view.php?id=369
- Bug Fix: Xcode property list for CEGUIExpatPaser was not producing the correct product name.
- Bug Fix: TreeItem binding was using CEGUI::String type instead of lua string (or utf8string type).  Thanks to Erik Hjortsberg.
- Bug Fix: MinizipResourceProvider was missing the function definition for setLoadLocal.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?p=22797#p22797
- Bug Fix: Resolve issues in Irrlicht renderer caused by not explicitly initialising the texture creation state flags.  See: http://www.cegui.org.uk/mantis/view.php?id=354
- Bug Fix: Interaction between scrollabrs and formatting for the multi-line editbox was incorrect causing scrollbars to incorrectly display under certain conditions.  See: http://www.cegui.org.uk/mantis/view.php?id=355
- Bug Fix: Incorrect content area would be used when laying out tab buttons.  See: http://www.cegui.org.uk/mantis/view.php?id=351
- Bug Fix: Sort direction in multi column list was incorrect.  See: http://www.cegui.org.uk/mantis/view.php?id=349
- Bug Fix: memory leak in TGAImageCodec when format not supported.
- Bug Fix: Memory leaks when bidirectional text support is enabled.
- Bug Fix: Implement / fix Tree::ensureItemIsVisible (damned amateurs).
- Bug Fix: IrrlichtRenderer would incorrectly clear the main render target (screen) during render to texture operations.  Thanks to Timo.  See: http://www.cegui.org.uk/mantis/view.php?id=348
- Bug Fix: ItemListbox inner rect / client area would not be updated in response to scrollbar visibility changes.  See: http://www.cegui.org.uk/mantis/view.php?id=346
- Bug Fix: TreeItem rendered string was not being invaliated in the setText function and one of the setTextColours overloads.  See: http://www.cegui.org.uk/mantis/view.php?id=347
- Bug Fix: TreeItem rendered string was not being invaliated in the setText function and one of the setTextColours overloads.  See: http://www.cegui.org.uk/mantis/view.php?id=347
- Bug Fix: TGA loader did not correctly handle flipping of image based on origin in the TGA file.  With thanks to 'Pompei2'.  See: http://www.cegui.org.uk/mantis/view.php?id=276.
- Bug Fix: ItemListbox had non-standard behaviour in single-select mode (and inconsistently differed to other list types in CEGUI).  See:http://www.cegui.org.uk/mantis/view.php?id=344
- Bug Fix: Update lua packages and binding so that input strings are passed as utf8 data, thus allowing unicode text to be passed via lua script files.  See: http://www.cegui.org.uk/mantis/view.php?id=302
- Bug Fix: Ensure that when splitting a RenderedStringTextComponent, we always split at least 1 char to the left hand side (else it could hang!)  See: http://www.cegui.org.uk/mantis/view.php?id=341
- Bug Fix: Issue where negative width / height for an area using tiled image would result in incorrect behaviour (eventually resulting in crash / memory exhaustion exceptions).  See: http://www.cegui.org.uk/mantis/view.php?id=340
- Bug Fix: Ensure falagard defined components (TextComponent, ImageryComponent, FrameComponent) are clipped to their defined area.  See: http://www.cegui.org.uk/mantis/view.php?id=339
- Bug Fix: Ensure we initialise the Rect objects that cache the various areas.  Issue flagged up via valgrind, see: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=10&t=4710
- Bug Fix: Ogre samples would die upon exit (at least in full-screen mode).  This was caused by trying to notify about display size changes after the CEGUI::System is destroyed.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?p=22091#p22091
- Bug Fix: Scale mouse wheel correctly for OIS under the Ogre sample base app.
- Bug Fix: Ensure size used for rendering window is using the same pixel aligned rounding as other parts of the system.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=3&t=4701
- Bug Fix: Add testing for __NetBSD__ so we compile correctly on that OS variant also.  See: http://www.cegui.org.uk/mantis/view.php?id=338.
- Bug Fix: Resizing host application window could leave dangling pointers to API level textures in cached geometry for RenderingWindows, causing access violation errors.  See: http://www.cegui.org.uk/mantis/view.php?id=337
- Bug Fix: static build / linking was not working correctly for autotools based builds.
- Bug Fix: Begin unification of support for build and version suffixes for Win32 and other builds.  This should basically fix module loading issues for autotools based MinGW builds configured with suffix / version numbers.
- Bug Fix: Remove unnecessary header includes and just declare the required functions as extern "C" for the static builds.  Static build preferences as to modules are controlled by which lib is linked, not by which header gets included - they all define the same functions!
- Bug Fix: Resolve some issues regarding window min/max size application.  Resolves: http://www.cegui.org.uk/mantis/view.php?id=157 amongst other issues.
- Bug Fix: The Windows utf-16 / wchar_t patch adding support for filenames encoded as utf16 was missing support for that facility in the DefaultResourceProvider::getResourceGroupFileNames function.  This fix adds that support.
- Bug Fix: Windows uses UTF-16 / wchar_t* types for filenames rather than UTF8, meaning the DefaultResourceProvider would fail to load files using international characters.  Via patch from 'itten': http://www.cegui.org.uk/mantis/view.php?id=334 (actual mods used a slightly sanitised version of the patch)
- Bug Fix: Resolve clipping issue caused because clipping regions were not always correctly pixel aligned.  See: http://www.cegui.org.uk/mantis/view.php?id=333.  NB: Went for the per-renderer fix as opposed to a single fix in, say, CEGUI::Window, in order that we ensure regions set from elsewhere in the future do not need to remember to use the PixelAligned macro.
- Bug Fix: Scrollbars for StaticText type widgets, if needed intially, would not show until after a redraw of the window was triggered.  See: http://www.cegui.org.uk/mantis/view.php?id=329
- Bug Fix: Issue where PropertyDefinition could throw if 'get' was called without having previously called 'set' - due to the implementation user string not getting created until then.  See: http://www.cegui.org.uk/mantis/view.php?id=332
- Bug Fix: TaharezLook frame window right edge was not rendering.  Thanks to sfb! :-p
- Bug Fix: Resolve issues where a Window's content was being clipped to it's parent window area(s) instead of it's own.  Note the following additional issues this fix exposes:
    - The 'clipped' attribute / setting for StateImagery in Falagard is broken and currently has no effect (this is due to clipping being done at GeometryBuffer level).  This issue is best demonstrated by the clipping now done on dragged list header segments.
    - Some layouts / falagard compound widgets have visible clipping artefacts: TextDemo's layout needs a couple of tweaks, and the WidgetLooks for TabControl (at least) have a couple of issues where component widgets do not join together correctly.
- Bug Fix: Conflict between Release and ReleaseWithSymbols. The customized premake file(s) will be committed later.
- Bug Fix: FrameComponent clipping was broken in the renderer rewrite.
- Bug Fix: Resolve bug where certain dimensions specified in looknfeel would give incorrect results.
- Bug Fix: DefaultRenderedStringParser did not support line breaks (which was different to the pre 0.7.x behaviour for text).
- Bug Fix: Ensure HorzExtent and VertExtent read-only properties are banned from being output to XML.  See: http://www.cegui.org.uk/mantis/view.php?id=325
- Bug Fix: Backport alpha blending fixes from trunk.  Decided to accept the small-ish interface changes (will not affect 99.9999% of users) to get these highly important fixes.
- Bug Fix: Update the 'extra' state initialisers for the GL renderer so that alpha test is disabled.
- Bug Fix: Resolve C++0x related compilation issue for MultiColumnList on (at least) MSVC++ 10 betas.
- Bug Fix: Support glBlendFuncSeparate via the GL_EXT_blend_func_separate extension as well as the native GL 1.4 support for it.
- Bug Fix: Resolve issues for the use of Ogre with CEGUI that were dependant upon which libs Ogre was built with. See: http://www.cegui.org.uk/mantis/view.php?id=320
- Bug Fix: Alpha blend issue for the Ogre renderer.
- Bug Fix: Alpha blending for D3D9 and D3D10 renderer modules.
- Bug Fix: Alpha blending issue that especially affected OpenGL FBO texture targets.  NB: Fixes for other renderers to follow soon.
- Bug Fix: Use correct GLint type (rather than long) in ApplePBTextureTarget to resolve potential compilation issues if GLint is typedef'd to an incompatible type.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=3&t=4553
- Bug Fix: Vanilla skin did not have the FrameWindow close button set as non-client window (meaning it was appearing in the main client area.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=10&t=4557
- Bug Fix: Issue where String object instances were being defined from forward ref declaration only (i.e. Missing CEGUIString.h include).  See: http://www.cegui.org.uk/mantis/view.php?id=317
- Bug Fix: Issue where certain window content would not have GeometryBuffer position / clipping information updated correctly depending upon order of operations.  Additionally sees that parent sized notification is now only selectively called when a window's parent is set/changed.  Should fix: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=3&t=4455

- Modified: Change comments in config.lua to clarify how CEGUI_EXTRA_PATHS should be used, and to give a more accurate example.
- Modified: Always output exception messages to stderr.
- Modified: Update embedded GLEW lib to the latest version (1.5.4), including modification to work around GL typedef differences in the OS X 10.4 SDK.
- Modified: Cleanup Irrlicht event pusher + don't force initially centred mouse position.
- Modified: Replace DriveIcons with a version we can be sure about the copyright status of.  Prior version appears to use non free imagery for some icons. 
- Modified: Replace try / catch / throw with macros CEGUI_TRY / CEGUI_CATCH / CEGUI_THROW.  This was done to attempt to fill this request: http://www.cegui.org.uk/mantis/view.php?id=242.  Note that there is no added setting for this, and no 'built in' mechanism that calls a user function.  The use of the macros does however allow users to pre-define the macros to do something different.  This said, tests show that the likelyhood of anybody actually being able to easily pull of a modification that allows exceptions not to be used - for example, by using the mechanism suggested in the first post of the topic linked in the mantis ticket - is pretty much non-existant.  At least having this provision allows them to prove it to themselves, because, as with the OP in that topic, they don't seem to believe you when you tell them ;)
- Modified: Update some window / looknfeel config to enable mouse event propagation for some compound widgets to restore common behaviours.  For: http://www.cegui.org.uk/mantis/view.php?id=318
- Modified: When frame window roll-up state is toggled, invalidate recursively so that child content visuals are forced to redraw.
- Modified: Update to use Automake 1.10
- Modified: Switch Xcode back to using a static set up for Irrlicht SDK (since they no longer appear to use a framework for mac)
- Modified: Changes to allow better control over rendering processes when using the Ogre renderer.
- Modified: Disable version suffix on MinGW / autotools build by default (because loading modules still does not work due to libtool using a '.' delimiter on *nix and '-' on MinGW).
- Modified: Clean up the scroll bar cpp/h files, applying code standards and formatting.
- Modified: Cleanup the CEGUIDefaultResourceProvider.cpp file and to start logging the full filename in errors as opposed to just the local resource name part.
- Modified: Make interface for banning Window properties from XML output public (and extend it a little, too)
- Modified: Update Demo7 to use a mapped window type that automatically gets the wobbly effect set for each instance.
- Modified: Update Demo7 to use the RenderEffectManager instead of creating the effects directly (though that is still supported, if someome wants to do that).
- Modified: In the samples, don't grab the mouse and keyboard in debug builds when using Ogre under X.
- Modified: Make Listbox::getItemAtPoint function public.  IMPORTANT: The Point object passed has changed from being a window local position to being a screen position!!  See: http://www.cegui.org.uk/mantis/view.php?id=319 

- Added: saveWindowLayout functions to WindowManager to enable saving directly to a named file.
- Added: explicit copy constructors for some of the basic data types; to aid in binding other languages :)  Thanks to Kulik.
- Added: Kulik's integrated animation system.  TODO: add XML writing code.
- Added: LayoutContainer classes to automate layout of child windows.  Contributed by Kulik (Martin Preisler).  Fills this: http://www.cegui.org.uk/mantis/view.php?id=214.
- Added: Window::getChildWindowContentArea (and associated virtual _impl functions) to allow separation of areas used for clipping and those used for positioning and sizing child content.  This is actually required to be able to reliably set up clipping for certain special cases - such as ScrollablePane - which would fail previously under some scenarios.
- Added: Support for useful help strings for properties defined in Falagard XML.
- Added: bootstrapSystem / destroySystem functions for the D3D based renderer modules + move samples over to using that func.
- Added: Functionality to enable client code to easily invalidate all cached rendering data, so that on the next redraw everything is regenerated.
- Added: MouseCursor::invalidate function to allow client code to invalidate cached mouse cursor geometry.
- Added: Setting to ListboxTextItem that allows text tag parsing to be disabled.
- Added: bootstrapSystem / destroySystem helpers on OpenGL renderer.  Preparation work to simplify / unify system creation for all official renderers (and make coming tutorial update easier to write!)  NB: same update to D3D renderer modules will follow some time soon.
- Added: RapidXML based XML parser module contributed by Jay Sprenkle.  See: http://www.cegui.org.uk/mantis/view.php?id=358 and http://www.cegui.org.uk/phpBB2/viewtopic.php?f=5&t=4822.
- Added: D3D11 Renderer code contributed by e3d_alive.  This requires the updated 0.7.x-r2 dependency packs to build.  Note that while the /build/ is tested and seems ok, currently the code itself is completely untested (will try to add a samples base app to test this over the weekend or next week).
- Added: Function to IrrlichtGeometryBuffer to retrieve the irr::video::SMaterial associated with the GeometryBuffer.  See: http://www.cegui.org.uk/mantis/view.php?id=363
- Added: Ability to specify initial mouse cursor position.
- Added: Function to allow explicit setting of the size at which to render the mouse cursor image.  See: http://www.cegui.org.uk/mantis/view.php?id=356
- Added: OgreTray skin - a recreation of the OgreSDKTrays UI as used in the Ogre samples.
- Added: Function to OgreRenderer that allows client code to change the Ogre::RenderTarget associated with the default rendering root.  Thanks to kornerr for suggesting and testing ;)
- Added: MinizipResourceProvider code as contributed by Jamarr (See: http://www.cegui.org.uk/mantis/view.php?id=345)  Also adding C++-ified versions of 'unzip' parts of Minizip project needed by the above.
- Added: Added new 'utf8string' type to tolua++cegui so we can support utf8 string data in lua scripts.  For: http://www.cegui.org.uk/mantis/view.php?id=302
- Added: Setting to control whether unhandled mouse input should be propagated back to the parent Window.  This is the code side of the fix for: http://www.cegui.org.uk/mantis/view.php?id=318.  Looknfeel updates (which will make the fix 'work') to follow shortly.
- Added: CEGUI::OgreRenderer::initialiseRenderStateSettings() function added in order to allow user to re-initialise the render states that CEGUI uses (and without any fear of the dreaded Ogre::RenderSystem::_beginFrame double-call).
- Added: The following support to Section specifications in Falagard:
    - controlValue attribute: specifies an optional 'test' value that the controlProperty's fetched value will be compared against when determining whether to render the section (if they match it is draw, otherwise it's not).  If this is empty the property is treaed as boolean (as before).
    - controlWidget attribute: specifies an optional widget identifier that will be used as the source of the property named by controlProperty.  This can be a child widget suffix or the special '__parent__' value.  If this is empty, the window being drawn is used as the source (as before).
- Added: Ability for PropertyLinkDefinition to create links back to the parent window via a special widget value of __parent__
- Added: 'end lock' mode to Scrollbar.  With this mode enabled the Scrollbar will automatically maintain it's position at the end of the scrollbar's travel (useful to implement auto-scrolling of content).  See: http://www.cegui.org.uk/mantis/view.php?id=315
- Added: Scrollbar::setConfig function allowing updating of multiple parts of the Scrollbar configuration at once (which allows the user to avoid triggering multiple unneccessary updates).  See: http://www.cegui.org.uk/mantis/view.php?id=316
- Added: New PropertyLinkTarget support to PropertyLinkDefinition.  This new support allows a one to many mapping for property links, allowing a single property on a containing window to update multiple child properties simultaneously.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=5&t=4666
- Added: MSVC++ / premake setting to allow some of the debug build STL iterator checks to be disabled, thus giving performance improvements to debug builds.  Generally these checks would only be useful for people debugging CEGUI itself, though they're still on by default - at least for now.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=10&t=4630
- Added: CEGUINullRenderer - useful for hdealess testing of CEGUI.  Written by Eugene Marcotte (thanks!)
- Added: New window update mode setting that allows some control over the calling of the Window::update function.  This defaults to WUM_VISIBLE for most window types, which is a large optimisation.  Many thanks to Jabberwocky.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=3&t=4500
- Added: Window::moveInFront and Window::moveBehind functions to allow fine grained control over the z-ordering of sibling windows.  See: http://www.cegui.org.uk/mantis/view.php?id=300
- Added: Provision to premake system to support addition of custom header and library search paths to any CEGUI project.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=10&t=4616
- Added: Add option in premake files to allow static builds of CEGUI to link against the DLL based dependencies and C/C++ runtime.  This helps some integration issues with other libs.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=10&t=4618 (my posts)
- Added: Facility in WindowRenderer interface to allow subclasses to indicate whether registered properties should be added to the 'ban' list for the target window.
- Added: New LineSpacing attribute for FreeType style fonts allowing override of line spacing in underlying font files.  From patch by 'codeka'.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=3&t=4605 and http://www.cegui.org.uk/mantis/view.php?id=326
- Added: Support for 'RenderEffect' attribute / setting on Falagard mapped types - allows automatic setup of render effects specified in schemes.
- Added: New RenderEffectManager singleton to act as a means to register RenderEffects with the system in a central place.  This will eventually be used with the scheme system to allow effects to be specified there.
- Added: Lua support for function Listbox::getItemAtPoint (actual binding needs regenerating, will come later after other possible updates to packages).
- Added: Notification message to OpenGL renderer ID string when glBlendFuncSeparate support is missing.
- Added: Add options to premake build that allow control over which build configurations will be available in the solution / project files.

- Deleted: Removed RightWindow enumerated value from CEGUI::Key::Scan enumeration.  Sorry if this breaks your stuff, but we needed this!
- Deleted: Remove unneeded 'keepme' files left over from the CVS days.
- Deleted: Remove the premake batch files for the unsupported 2002 version compiler.

- Documentation: Remove reference to premake 3.1 and link to our custom premake instead.
- Documentation: Add documentation file that has licensing info for the media files.
- Documentation: Fix issue where we referenced non-existent class.  See: http://www.cegui.org.uk/mantis/view.php?id=331  NB: Will upload fixed version to docs/current later on today.
- Documentation: Fix issues where references were made to incorrect or non-existant classes.  See: http://www.cegui.org.uk/mantis/view.php?id=330 NB: Will upload fixed version to docs/current later on today.
- Documentation: Update event name documentation with information about the specific EventArgs subclass that gets passed to subscibed event handlers.  See: http://www.cegui.org.uk/mantis/view.php?id=321
- Documentation: Misc. minor fixes and updates to some of the docs.


<b>Release 0.7.1</b>
- Bug Fix: Ensure --includedir configure option is respected.
- Bug Fix: Issue of Window's local GeometryBuffer translation not being reset when Window gets given a surface after initial creation.
- Bug Fix: Issue of Window's RenderingWindow rotation pivot point not getting updated as window's area size changes.
- Bug Fix: Issue of rendering window surfaces not getting correctly transferred under all circumstances.
- Bug Fix: Double-deletion of non-system created ImageCodec when linking statically.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=10&t=4414
- Bug Fix: Do not log non-errors as errors when using minibidi.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=10&t=4356
- Bug Fix: MultiColumnList bug where row inserted into sorted list was not passing on input row_id value.
- Bug Fix: Static builds linked (incorrectly) against runtime DLLs. This is now fixed.
- Bug Fix: Change the size calculations for the editbox portion in the WidgetLook definitions for the Combobox.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=9&t=4382
- Bug Fix: update package config files to specify the correct library names when a build suffix is used.
- Bug Fix: OpenGL based texture targets would fail after calls to grabTextures / restoreTextures.  NB: Still to test fix on Apple and WGL.
- Bug Fix: in OpenGL Texture, only allow a single grabTexture to occur.
- Bug Fix: UnifiedMaxSize property had incorrect default value string.  See: http://www.cegui.org.uk/mantis/view.php?id=313
- Bug Fix: For Unified metrics, in the divide by zero case, set the compoent part to zero (not correct, but maybe argued better than doing nothing). See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=3&t=4403
- Bug Fix: Set size on dialogs in the ScrollablePane demo in order that the drag-sizing code works right :-p
- Bug Fix: ScrollablePane issues:
    - Broken hit-testing of content initially outside the view pane (this was broken in 0.7.0 when inner-rect fix was made).
    - Broken relative co-ords of added content (incorrectly used size of content pane as base rather than ScrollablePane inner-rect).
    - Broken positioning of (0, 0) point of content pane (prevented content from being offset correctly).
- Bug Fix: Ensure base co-ords used for window to screen conversions are pixel aligned.  This fixes issues caused by per-window geometry buffer translations (and associated clippers) not being pixel aligned and causing blurred imagery.
- Bug Fix: Remove redundant offset translation from OpenGL renderer module (was not doing anything because it should have been before the 'get', but this offset is not needed anyway).
- Bug Fix: issue in MultiLineEditbox where caret position gets messed up when backspace deleting the last character.
- Bug Fix: Ensure looknfeel based content (auto window content) is layed out prior to notifying other content about size changes, this is required because the inner-rect area may rely on the size or position of this auto window content.
- Bug Fix: Issue where CEGUI::Window check for size change did not consider the fact that although the outer rect has not changed, the inner rect still may have - for example as a result of imagery auto-scaling.
- Bug Fix: Textures in cached geometry may become invalid after a display / host window resize, so we must ensure all cached geometry is regenerated by invalidating all windows.
- Bug Fix: Window rect area / window position would not always be updated when using alignments other than top/left.
- Bug Fix: Updates required to work with Irrlicht 1.6 final release.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=10&t=4393.
- Bug Fix: XMLParser::initialise was not being called when linking statically.
- Bug Fix: Issue where a root GUISheet with mouse pass through enabled would still consume a mouse button down event if the window was not already active.  See: http://www.cegui.org.uk/mantis/view.php?id=309
- Bug Fix: D3D9 renderer was not setting View matrix back to identity prior to rendering, thus allowing potential funkiness to ensue ;)
- Bug Fix: Minor tweak so premake scripts work correctly when using premake 3.7.
- Bug Fix: Issue where window positions with purely absolute positioning would not trigger update of the the GeometryBuffer translation vector under various circumstances.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=10&t=4365.
- Bug Fix: In MCL insertion point when adding content to a sorted list did not correctly take into account the sort direction.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=3&t=4360
- Bug Fix: Resolve issue where a non-splitting RenderedStringComponent could cause a hang in the RenderedStringWordWrapper class.  See: http://www.cegui.org.uk/mantis/view.php?id=306
- Bug Fix: The Editbox classes would incorrectly parse the input text and potentially cause exceptions based upon user input (See: See: http://www.cegui.org.uk/mantis/view.php?id=308).  This fix is a multi-part enhancement in order to correctly and cleanly enable effective disabling of parsing, consisting of the following:
    - Add static DefaultRenderedStringParser to Window for use when normal parsing is disabled.
    - Add member functions, property and event based around enabling and disabling text parsing.
    - Update editbox classes to disable parsing by default.
- Bug Fix: Resolve issue with FrameWindow content layout for cases where FrameWindow is initially hidden.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=10&t=4357
- Bug Fix: Resolve (hopefully, anyway) issues relating to our not checking for support for NPOT textures in the OpenGL renderer (NB: WGLPBuffer versio still to be tested). See: http://www.cegui.org.uk/mantis/view.php?id=307
- Bug Fix: Irrlicht renderer issues where driver capabilities were not checked correctly before using possibly unsupported facilities.  See: http://www.cegui.org.uk/mantis/view.php?id=305
- Bug Fix: Issue of MultiLineEditbox not being initialised correctly (no initial terminating \n being set).  See: http://www.cegui.org.uk/mantis/view.php?id=304
- Bug Fix: Do not optimise debug build on the Mac.
- Bug Fix: Fix incorrect SVN URLs in documentation.
- Bug Fix: Crash in Ogre based texture target, where we may inadvertently restore a deleted viewport to the render system.

- Modified: Introduce OpenGLTextureTarget common base class for all the various texture targets supported.
- Modified: Allow use of alternative names for named areas in the Listbox WidgetLook (looknfeel).  This allows unified names for Listbox and ItemListbox in order that the same WidgetLook definition may be used for both.  See: http://www.cegui.org.uk/mantis/view.php?id=314
- Modified: Correct license information in the TreeDemo files.
- Modified: Update license info from LGPL to MIT (change applied with original author's permission).
- Modified: Updated the Groupbox license to MIT. This has been approved by Levia, the author.
- Modified: Changes to FontDemo:
    - Auto load all fonts in resource group "fonts"
    - Each language now has a 'preferred font' name specified.
    - Language only shows in list if preferred font is loaded.
- Modified: Allow Window subclasses to override the code that sets the various window region rect areas (inner, outer, clippers and hit-test).
- Modified: Update CEGUI premake system for use with static dependency libraries in static builds.  IMPORTANT NOTE: All MSVC++ users - you MUST now use the new 0.7.x-r1 dependency packages and not the previous 0.7.x packs.
- Modified: Optimise FrameWidow drag-sizing code so that Window::setArea_impl is not called twice when a sizing operaion involves two edges.
- Modified: Some optimisations in Falagard StaticText renderer to reduce unneccessary text formatting calls (which have the potential to be very expensive).

- Added: Functions to DragContainer to support a custom fixed offset from which the container will always be dragged from.
- Added: DragContainer::pickUp function to allow user code to programatically pick up a sticky mode DragContainer.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=10&t=4406
- Added: Definitions for Combobox and Progressbar in Vanilla looknfeel and scheme.
- Added: Optional extended input event injectors for mouse button click, double-click and triple-click events.  NB: Lua bindind needs regenerating.  See: http://www.cegui.org.uk/mantis/view.php?id=299.
- Added: Setting to System to disable the automatic generation of mouse button click, double-click and triple-click events.
- Added: Package config file for CEGUI / Ogre.  See: http://www.cegui.org.uk/mantis/view.php?id=312.
- Added: Basic math operator overloads to UVector2 that take a single UDim.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=3&t=4403
- Added: Window::invalidate(const bool) function to enable recursiv invalidation of all child content for a window as well as the window itself.  NB: This function replaces the old Window::invalidate function (with no args), which is now deprecated and will be removed at some future time (circa 0.8.x)
- Added: New events FrameWindow::EventDragSizingStarted and FrameWindow::EventDragSizingEnded.
- Added: User configurable System level global custom RenderedStringParser to be used whenever parsing is enabled and no custom parser is set for a window.
- Added: Expanded tags supported in BasicRenderedStringParser to expose the existing padding and vertical alignment support, and to add support for specifying image dimensions.
- Added: VertExtent and HorzExtent properties added to Falagard StaticText renderer to return current pixel extents of formatted text.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=10&t=4363

- Deleted: Remove Commonwealth, Iconified and Sword fonts due to possible licensing issues.


<b>Release 0.7.0</b>
- Complete rendering subsystem / renderer module rewrite:
    - Window system now caching at the geometry level, eliminating vast amounts of redraw calculations.
    - Support for caching imagery to texture, eliminating large amounts of redraw work.
    - Support for targeting Window sub-heirarchies to separate rendering surfaces (still many user-friendliness work and other fixes to do here).
    - Support for a RenderEffect system allowing custom geometric and shader based effects for Window objects.
    - Support for three axis rotation of texture backed Windows and other GeometryBuffer content.
    - Additional notes:
        - Removes: Support for D3D 8.1 based renderer.
        - Removes: Support for compiling against Irrlicht versions below 1.4.
        - DirectFB support currently broken.

- Added new string rendering enhancements, current version provides:
    - Extensible RenderedStringParser system.
    - Base support for parsing formatting tags in strings:
        - Support for [font] tag to enable multiple fonts per text string.
        - Support for [colour] tag to enable multiple colours per text string.
        - Support for [image] tag to enable embedding of images in strings.
        - Support for [window] tag to enable aligning child window/widget content in-line with other string rendering.
- Added: Added 'sticky' mode to DragContainer.  See: http://www.cegui.org.uk/mantis/view.php?id=129
- Added: Common optional Falagard based NamedArea of 'inner_rect' that is looked up and used for the inner/client area of a window (unless other specific named areas are used by a specialised WindowRenderer).  Final addition for: http://www.cegui.org.uk/mantis/view.php?id=260.
- Added: Option for the caret used with Editbox and MultiLineEditbox to blink with an adjustable timeout / blink period.  Implemented for: http://www.cegui.org.uk/mantis/view.php?id=227
- Added: possibility for time based update of a WindowRenderer (allows WR based animation / automation).
- Added: option to disable building the CEGUI::DefaultLogger object.  NB: In this case a suitable alternative must be provided and instantiated prior to creating the main CEGUI::System object.  See: http://www.cegui.org.uk/mantis/view.php?id=243
- Added: Option to disable the use of the freetype2 external library.  See: http://www.cegui.org.uk/mantis/view.php?id=240
- Added: Option to configure CEGUI so that it does not require the PCRE dependency (disabling this will cause attempts to set the validation string - such as what the spinner does in it's constructor - to throw InvalidRequestException).  See: http://www.cegui.org.uk/mantis/view.php?id=241
- Added: Option to autotools build to enable some configuration of the version suffix that's now appended on those builds.
- Added: Option to autotools build to specify a general suffix that's added to the name of binary output for autotools builds.  This enables the installation of multiple versions based upon different configuration and build options (similar to what we have with MSVC++ and the _d suffix for debug builds).  See: http://www.cegui.org.uk/mantis/view.php?id=274
- Added: Facility for resource system to load all resources matching a given pattern from a specified resource group (on a per resource type basis).  For: http://www.cegui.org.uk/mantis/view.php?id=190
- Added: Add property to XercesParser to access the default schema resource group (allows setting of this without needing to explicitly link to XercesParser module lib).
- Added: Event notification via WindowManager for Window object creation and destruction.
- Added: Added bi-directional text support contributed by Assaf Raman.  See: http://www.cegui.org.uk/mantis/view.php?id=268.  NB: Not supported by MultiLineEditbox (yet).
- Added: Implementation of an ImageCodec that goes via the Ogre image loading facilities.  NB: This is provided as an 'integrated' class as opposed to a loadable module since it's a more consistent approach for an engine specific entity such as this.
- Added: Implementation of an ImageCodec that goes via the Irrlicht image loading facilities.  NB: This is provided as an 'integrated' class as opposed to a loadable module since it's a more consistent approach for an engine specific entity such as this.
- Added: Support for adding WindowRendererFactory objects via a template function to allow CEGUI to create and manage the factory instances (rather than having to have them pre-created).
- Added: Dialog based implementation of a renderer selector for the Mac.
- Added: MSVC++ 2008 batch files for project generation, cause the premake support seems to work.
- Added: Event notifications for main resource actions (create, destroy, replace).
- Added: Doxygen based supporting documentation and tutorials.
- Added: Doxygen based version of Falagard skinning documentation (which will now become the only maintained version of that material).
- Added: Template based system for WindowFactory creation:
    - Removes the need to manually create supporting structure when adding new Window types.
    - Dispenses with the need to use the macro nastiness previously employed.
    - No longer need to have statically created factories laying around.
- Added: Apply patch: http://www.cegui.org.uk/mantis/view.php?id=275 that adds some extra support for TreeItem to the lua module.

- Removed: deprecated Window::doRiseOnClick function.
- Removed: Formatting related functions from Font.
- Removed: Duplicate text formatting enumerations - now using a single version (the HorizontalTextFormatting and VerticalTextFormatting enums in the CEGUIFalEnums.h file)
- Removed: Apple specific version of resource setup in samples (no longer required due to other improvements).

- Modified: Changed key handling in editbox classes to allow user subscribed events to 'consume' keys and prevent the usual processing from occuring.
- Modified: CEGUI::Exception to derive from std::exception (for: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=5&t=4267 and others from waaay back).
- Modified: Made CEGUI::LuaScriptModule constructor / destructor private - access is now via LuaScriptModule::create and LuaScriptModule::destroy static functions.
- Modified: Made CEGUI::System constructor / destructor private - access is now via System::create and System::destroy static functions.  Additionally, first parameter changed from being a Renderer pointer to a Renderer reference (reinforces that it may not be 0).
- Modified: Switched to a single unified constructor for LuaScriptModule.
- Modified: Change names of renderer modules and libs produced under premake/MSVC++ to match those produced by other methods (i.e. CEGUIOpenGLRenderer instead of OpenGLGUIRenderer)
- Modified: Change access protection on CEGUI::Tree::getItemAtPoint from protected to public.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?p=15576#15576
- Modified: Switch from libtool ABI versioning to release versioning.  This is related to this: http://www.cegui.org.uk/mantis/view.php?id=197 in reagrd to our continual breaking changes, but also solves issues of plugin/loadable module version conflicts, and effectively allows side-by-side installations of multiple versions of the binary.
- Modified: Prevent copy and assignment for Singleton based objects (the compiler error helps people spot common usgae mistakes).  See: http://www.cegui.org.uk/mantis/view.php?id=203
- Modified: Changed the system default 'single-click' timeout from 0.2 to 0 (infinite).  See: http://www.cegui.org.uk/mantis/view.php?id=209
- Modified: Changed default state of inherited tooltip text from false to true.  See: http://www.cegui.org.uk/mantis/view.php?id=204
- Modified: Replaced the old config file support with something more comprehensive and useful. See: http://www.cegui.org.uk/mantis/view.php?id=189
- Modified: Disable optimisation in the ReleaseWithSymbols config. See: http://www.cegui.org.uk/mantis/view.php?id=293
- Modified: Made ListboxItem::setText virtual.
- Modified: FreeTypeFont to output more detailed error info when creating a font face fails.
- Modified: XMLParser now becomes a PropertySet.
- Modified: Relax requirement that the target of a window alias exists before creating the alias.
- Modified: Relax requirement to have imageset / font names specified in schemes along with the names of files.
- Modified: Simplify and (largely) unify resource group initialisation for sample base apps.
- Modified: Added build and system information to the logged version string.
- Modified: Window::isHit (and some other related funcs) has an added boolean to allow disabled windows to be correctly hit-tested when needed.
- Modified: Changed the way that a 'Window Renderer Set' loadable module is composed.  Moving away from using a macro based approach to a class based approach.  This makes creation of these modules much easier and cleaner; it's also more transparent, since everyone understands classes, whereas probably nobody knew what was going on behind those macros!
- Modified: Update the Falagard window renderer set to use the new class based specification system.
- Modified: Completely replaced old Xcode project with a new one.
- Modified: Rewrote Mac bundle loading to look in 'PlugIns' locations instead of 'Resources' locations.
- Modified: Change Sample base application so that on that Mac it successfully fetches the path of the datafiles directory within the app bundles Resources (now we don't have to rely on working directory being unmodified).
- Modified: Core resource loading (Scheme, Font, Imageset) to support differing actions based upon loading a resource with a name that already exists in the system.
- Modified: Regular expression library use abstracted via CEGUI::RegexMatcher (available internally only at the moment!)
- Modified: PCRE usage now via a PCRE based implementation of CEGUI::RegexMatcher.
- Modified: Internal Window class changes to (try to) overcome confusing usage of all those d_screen* rect members and a bunch of getters with unclear names:
    - getUnclippedPixelRect is renamed to getUnclippedOuterRect
    - getUnclippedInnerRect is unchanged.
    - getPixelRect is renamed to getOuterRectClipper and is intended only for the use of rendering calculations.
    - getInnerRect is renamed to getInnerRectClipper and is (again) intended only for the use of rendering calculations.
    - Added a getUnclippedRect function that can return either inner or outer area dependant upon the value passed.
    - Added a getClipRect function that can return either inner or outer area dependant upon the values passed.
    - Added a new area specifically for hit testing and such, fetched with getHitTestRect.  NB: This was added since the other area rects are not reliable for hit testing due to the fact things may or may not being clipped when rendered to a texture target.
- Modified: Input injection and Event changes:
    - CEGUI::System no longer propogates input events (those that are injected) recursively.  CEGUI::Window will however do this for key events by default.
    - CEGUI::Window marks all mouse input events as handled by default.
    - CEGUI::GUISheet (DefaultWindow) overrides the CEGUI::Window mouse handling to not mark events handled if the GUISheet is a root window with mouse passthrough enabled.
    - EventArgs::handled member has changed type from bool to uint.
- Modified: Complete restructuring of the source tree (for cleanup and improved consistency reasons, amongst other things).
- Modified: FontDemo changes:
    - Added Vietnamese example text.
    - Added Japanese and Korean text + fonts
    - Select a default valid font when selecting a different language
    - Changed font in language list, because one was invisible (missing glyphs)
- Modified: Warn user during samples premake, when both DX9 and DX10 are defined for static builds.

- Bug Fix: issue where invalid values were accepted by Window::setAlpha, causing renderer dependent problems.
- Bug Fix: issue with Tree::getNextSelectedItemFromList not processing branches correctly.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?f=3&t=4239

- Bug Fix: Made implementation data in FalagardEditbox protected.
- Bug Fix: Issue where use of lua 5.1 with the binding generator explicitly required lua to have been built with LUA_COMPAT_VARARG defined.  This fixes the issue, but removes compatibility with the old lua 5.0 version.  See: http://www.cegui.org.uk/mantis/view.php?id=211
- Bug Fix: Isse where some Font accessor functions were non-const.  See: http://www.cegui.org.uk/mantis/view.php?id=199.
- Bug Fix: resolve warnings about discarded return type qualifiers.
- Bug Fix: resolved issue where spinner would use scientific notation, and also suffer various other precision related anomolies (now using modified function from stringencoders lib).  See: http://www.cegui.org.uk/mantis/view.php?id=123.
- Bug Fix: Resolve a load of warnings and C++ standards compliancy issues.
- Bug Fix: Correct a whole load of EOL issues.
- Bug Fix: Issue where lua error function default state was not initialised in constructor taking an existing lua state.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?t=4023
- Bug Fix: Issue where ToggleButton WindowRenderer was not correctly using defaults for missing states.  See: http://www.cegui.org.uk/mantis/view.php?id=291

- Bug Fix: Resolve missing properties and functionality in Vanilla looknfeel.  (http://www.cegui.org.uk/mantis/view.php?id=281).
- Bug Fix: PopupMenu was not resizing correctly in response to parent size changes; fix implemented in ItemListBase so should catch other similar issues too.  (http://www.cegui.org.uk/mantis/view.php?id=266).
- Bug Fix: Changes to compile as cleanly as possible with "-Wall -Wextra -ansi -pedantic" options.  Basically inspired by: http://www.cegui.org.uk/mantis/view.php?id=257.
- Bug Fix: Apply (most of) patch: http://www.cegui.org.uk/mantis/view.php?id=271 for FreeBSD support.

- Bug Fix: Resolve stack overflow issue when tooltip appears directly under the mouse (http://www.cegui.org.uk/mantis/view.php?id=264).
- Bug Fix: Resolve issue where System would try to invoke member functions on a null tooltip.  (http://www.cegui.org.uk/mantis/view.php?id=263)
- Bug Fix: Resolve issue caused by the removal of the ILvoid typedef from newer DevIL releases.  (http://www.cegui.org.uk/mantis/view.php?id=259)
- Bug Fix: Issue with CEGUI::LuaFunctor usage where lua function references were getting released by accident.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?t=3727
- Bug Fix: Added a couple of missing member initialisers.  NB: This was almost always totally harmless, honest :-p


<b>Release 0.6.2</b>
- Added: Support for TreeEventArgs in the lua scripting module (patch from kripken, http://www.cegui.org.uk/phpBB2/viewtopic.php?t=3704)
- Added: ScrolledItemListBase::ensureItemIsVisibleVert and ScrolledItemListBase::ensureItemIsVisibleHorz members to allow scrolling lists programmatically to ensure a specified item is visible.  See: http://www.cegui.org.uk/mantis/view.php?id=228
- Added: Added ability to specify a function to be used as the error handler in calls to lua_pcall.  See: http://www.cegui.org.uk/mantis/view.php?id=239
- Added: GUI Renderer module and supporting samples base app for DirectFB (http://www.directfb.org/).  Contributed by Keith Mok.  See: http://www.cegui.org.uk/mantis/view.php?id=233.  Needs additional testing!  SKIP ON MERGE - trunk will get it's own version via the mantis patch (then be rewritten for the new renderer model).
- Added: Member to CEGUI::TreeItem to allow removal of sub-items.  see: http://www.cegui.org.uk/phpBB2/viewtopic.php?p=15563#15563
- Added: Templatised addFactory static function to WindowFactory manager that allows the system to create - and therefore own - custom window factory objects; thus alleviating potential cleanup issues when using custom factories.  See: http://www.cegui.org.uk/mantis/view.php?id=249.

- Modified: Modify Tree::setItemSelectState(TreeItem* item, bool state) to recurively check subitems also (else we fail when trying to set the selected state on a second level (or greater) item).  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?p=16197#16197
- Modified: Forward CEGUI::ScriptException from within the CEGUI::System script execution functions as opposed to translating them into less useful CEGUI::GenericException.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?t=3595
- Modified: Enhanced existing logging to include memory addresses when an object is created or destroyed (for most objects).  See: http://www.cegui.org.uk/mantis/view.php?id=224
- Modified: Added warning to WindowManager::loadWindowLayout documentation regarding possible invocation of incorrect overload when using a C string literal for the 'name_prefix'. (Issue is to be resolved in trunk.  Maintaining ABI and API compatibility with previous v0-6 releases prevents a fix in this branch).
- Modified: Tree Code / documentation reformatting, correction and cleanup.
- Modified: Mark Tree and related classes as deprecated.

- Bug Fix: Issue in ComboDropList would cause InvalidRequestException whenever input capture was lost and the highlighted item was different to the last click-selected item.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?t=3693.
- Bug Fix: Disable MSVC++ 4251 warning coming from CEGUITreeItem.h
- Bug Fix: Event connection objects returned to lua subscribeEvent calls did not have the connected or disconnect members available for use (making the connection object useless).
- Bug Fix: TinyXML parse failures were going unchecked.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?t=3688.
- Bug Fix: Lua script module based 'executeScriptedEventHandler was still not returning correct value (missed when I did the LuaFunctor version of the same, see: http://www.cegui.org.uk/mantis/view.php?id=225 for original issue).
- Bug Fix: Hopefully resolve issue where the use of FreeImage codec could result in pixel format of loaded data being incorrect.  See: http://www.cegui.org.uk/mantis/view.php?id=230.
- Bug Fix: There was an issue where Windows could be created during system destruction - this fixes that by introducing a 'locked' state for WindowManager whereby any attempt to create a Window throws an InvalidRequestException.  See: http://www.cegui.org.uk/mantis/view.php?id=250.
- Bug Fix: ScriptModule bindings were destroyed out of sequence meaning event handlers could still be fired that needed CEGUI bindings to exist.  See: http://www.cegui.org.uk/mantis/view.php?id=245.
- Bug Fix: The functionality of the "rise on click" setting was totally broken (prize for longest standing issue?).  See: http://www.cegui.org.uk/mantis/view.php?id=244.
- Bug Fix: When using the scrollwheel to change a CEGUI::Slider value, the direction of movement was the opposite to what would have been expected.  See: http://www.cegui.org.uk/mantis/view.php?id=238.
- Bug Fix: PropertyDim documentation did not reflect the updated abilities of the class, and the documentation for the argument 'type' was not clear about how it should be used with regards to affecting interpretation of the property accessed.  Related to: http://www.cegui.org.uk/mantis/view.php?id=247.
- Bug Fix: Endian problem with CEGUI::colour.  This change should fix this: http://www.cegui.org.uk/mantis/view.php?id=229
- Bug Fix: The Window::getChild(const CEGUI::String&) function was incorrectly made recursive after the 0.5.x series of releases.  This fix restores the correct behaviour and adds a Window::getChildRecursive(const CEGUI::String&) function for the highly expensive recursive case.  See: http://www.cegui.org.uk/mantis/view.php?id=237
- Bug Fix: The C++ side of the lua based event mechanism would always return true as if the event were handled, even if some other boolean value (i.e. false) were returned from the lua side.  See: http://www.cegui.org.uk/mantis/view.php?id=225
- Bug Fix: Resolve issue where events were still being injected into an invisible GUI sheet / root window.  See: http://www.cegui.org.uk/mantis/view.php?id=226
- Bug Fix: null window pointers to add/remove functions of TabControl were unchecked and would cause crashes.  See: http://www.cegui.org.uk/mantis/view.php?id=232
- Bug Fix: Resolve incompatibility issue with Xerces-C++ 3.  See: http://www.cegui.org.uk/mantis/view.php?id=235
- Bug Fix: Window::getChild and Window::recursiveChildSearch would use the starting window's prefix when testing the prefix + name case, this is incorrect and should have been using the prefix of the child being tested (load 2 windows from layouts, using different prefixes.  Add the second layout to the first as a child, then call getChild on the first layout window, passing the name of the second layout window, prior to the fix the call would have failed to find the child).
- Bug Fix: Resolve inconsistency where Window::isChild did not consider the Window name prefix, whereas Window::getChild did. See: http://www.cegui.org.uk/mantis/view.php?id=215.
- Bug Fix: Potential crash regarding sorted column ID, when queried by the property system.
- Bug Fix: the value returned by System::getWindowContainingMouse was only updated when the mouse was moved, this caused potenial issues when windows were moved, sized, created, destroyed, or had their visible or enabled states changed.  See: http://www.cegui.org.uk/mantis/view.php?id=213.
- Bug Fix: Programmatically made changes to Combobox selection were not reflected in the Editbox component of the Combobox.  See: http://www.cegui.org.uk/mantis/view.php?id=220.
- Bug Fix: Vector out of bounds in Window::update (see: http://www.cegui.org.uk/mantis/view.php?id=221)
- Bug Fix: Win32 helper did not consider window farme / decorations when creating windows, so the client area was always smaller than requested.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?p=15524.
- Bug Fix: 'else' within preprocessor conditional sections with no guarantee that there was a prior 'if'.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?p=15524.
- Bug Fix: Fix a couple of minor rendering issues with TaharezLook/ProgressBar.
- Bug Fix: Resolves a bug where the progress content was drawn into, rather than clipped by, the intersection of the the full progress area and the current progress area.  NOTE: People relying on the old buggy behaviour can reproduce the same effect by multiplying appropriate part(s) of thier imagery area definitions by the "CurrentProgress" property in their looknfeel files.
- Bug Fix: MinGW configure/make was not building with glew correctly.
- Bug Fix: Issue with Tree related properties casting to Listbox.  See: http://www.cegui.org.uk/mantis/view.php?id=218
- Bug Fix: Resolve issue where iterator at begining of range was decremented uncheked. See: http://www.cegui.org.uk/phpBB2/viewtopic.php?t=3408


<b>Release 0.6.1</b>
- Added: Batch files to invoke premake for VC9 files (seems to work fine)
- Added: Added a supported value to represent infinity to enable the click generation timouts to be set to "no timeout".  See: http://www.cegui.org.uk/mantis/view.php?id=208
- Added: Added Window::appendText and Window::insertText member functions.  See: http://www.cegui.org.uk/mantis/view.php?id=195
- Added: Initial version of a sample base application using Direct3D 10.
- Added: Initial code for the D3D 10 GUI Renderer, originally contributed by Rajko Stojadinovic.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?t=2919
- Added: IrrlichRenderer had no facility for notifying of display size changes.  This adds a setDisplaySize member for that purpose.  (Part of fixes for: http://www.cegui.org.uk/mantis/view.php?id=187).
- Added: Logging of renderer resize event notifications (prelim work for issue: http://www.cegui.org.uk/mantis/view.php?id=187)
- Added: New drag and drop demo.  Originally written to aid in debugging of an issue, but is otherwise useful as an example :)
- Added: Added FPS readout in sample base app for Irrlicht.  (See: http://www.cegui.org.uk/mantis/view.php?id=176).

- Modified: Changed Xcode build for the renderer frameworks so that headers retain their original subdirectory location; this aids in keeping client code portable.
- Modified: Refactored tab removal code to eliminate repetition.
- Modified: On linux, use installed system versions of tolua++ and TinyXML libraries if available (can be disabled to force continued use of internal versions).  See: http://www.cegui.org.uk/mantis/view.php?id=198

- Major update of Mac Xcode project.  This attempts to achieve the following:
    - Update all existing targets in relation to added and removed source files.
    - Resolved some minor issues with custom scripts when rebuilding up to date targets.
    - Added targets for Demo6, Demo7, Demo8, DragDropDemo, InstancedWindows, TextDemo and TreeDemo (completing the set).
    - Added target for ceguitolua++ framework (needed for lua support and for lua samples to run).
    - Use of precompiled dependencies package from within local tree (upload to follow shortly, pending resolution of final remaining issues).
    - Dependency frameworks will now be embedded within whichever component uses them (as opposed to needing separate installation).
    - Sample apps now correctly work with embedded CEGUI frameworks and so should run anywhere without additional installation.
    - Modify samples app packaging to symlink the frameworks and datafiles, as opposed to actually copying - this vastly reduces the footprint of the development directory (at a small cost of flexibility).
    - symlink the output sample apps into the ./Samples/bin directory (using subdirs for each config)
    - Added required define in CEGUIConfig.h for Lua support
    - Updated default ImageCodec in CEGUIConfig.h to be SILLY
    - Big cleanup of the various targets so that common settings (virtually all settings, actually) can be set once at the project level rather than needing to be set separately on each target.

- Bug Fix: Deleting/removing a menu item from a menu when the item had an active popup would result in a dangling pointer to the deleted/removed item.
- Bug Fix: line endings and set missing svn:eol-style on all Tree related code files.
- Bug Fix: Injection of mouse movements and mouse positions which did not actually reflect a change of mouse cursor position were still firing events and triggering side effects.  See: http://www.cegui.org.uk/mantis/view.php?id=202
- Bug Fix: ItemListbox::removeItem() was not checking if removed item was the one referenced in d_lastSelected, so was leaving a dangling pointer.  See: http://www.cegui.org.uk/mantis/view.php?id=206
- Bug Fix: The docs for the list widgets stated that the insert member would insert anitem after a given item, whereas the widget actually inserted the item before the given item.  See: http://www.cegui.org.uk/mantis/view.php?id=205
- Bug Fix: Exception message in postD3DReset member of the D3D renderers was incorrectly stating the exception as coming from from preD3DReset.  See: http://www.cegui.org.uk/mantis/view.php?id=207
- Bug Fix: double deletion issue in Corona based ImageCodec.
- Bug Fix: MacRendererSelector had uninitialised member variable, causing incorrect behaviour.
- Bug Fix: CEGUISamplesConfig.h is for Mac only now - removed conditionals that would bring in these options for Win32 (which uses premake).
- Bug Fix: Fixed comment blocks to eliminate a constant stream of warnings (gcc) when building anything CEGUI related.
- Bug Fix: Need to bring in CEGUIConfig.h when building CEGUILua.cpp in case we're on a Mac.
- Bug Fix: Bug in CEGUIDevILImageCodec in which ILinfo structure is not inititalised to 0s prior to usage, causing random crashes.
- Bug Fix: inclusion of config.h MUST be protected by a conditional that checks HAVE_CONFIG_H.
- Bug Fix: Between the 0.5.0 and 0.6.0 releases the System::setDefaultXMLParserName function was bastardised to perform a function other than its intended purpose.  This fix restores the intended behaviour of setDefaultXMLParserName and adds functions for setting the XML parser after System instantiation correctly.  See: http://www.cegui.org.uk/mantis/view.php?id=186
- Bug Fix: Issue of missing OpenGL render state initialisation when multitexture support is available.  See: http://www.cegui.org.uk/mantis/view.php?id=201.  NB: This also adds use of GLEW library (external (autotools) or embedded (all platforms)).
- Bug Fix: uncomment part of cegui.lua configuration script that allows use of option to have Ogre in samples.
- Bug Fix: pragmas for link libs in Ogre base app were incorrectly dependant on _WIN32 macro instead of _MSC_VER macro.
- Bug Fix: Added extra pragma lines to bring in required OIS lib for the Ogre base app.
- Bug Fix: Ogre base app now uses numKeyboards (was numKeyBoards) from OIS; this is what the OIS from the Ogre deps expects.
- Bug Fix: Fixed documentation for MouseButton enumeration.  Thanks to 'alphasnd'.
- Bug Fix: UpdateEventArgs::d_timeSinceLastFrame was not being initialised in constructor.
- Bug Fix: Use linux SimpleTimer::currentTime for Apple Macs also.  Thanks go to alphasnd, see: http://www.cegui.org.uk/phpBB2/viewtopic.php?t=3247
- Bug Fix: Resolve compilation issue on older gcc versions (gcc 3.x) where casting using functional notation is not good.  See: http://www.cegui.org.uk/phpBB2/viewtopic.php?t=2317
- Bug Fix: TabControl was subscribing to EventTextChanged on added content windows, but not releasing the connection when the content window was removed - causing UnknownObject exceptions and possible crashes when attempting to change the text on a window after it had been added to and then removed from a TabControl.  See: http://www.cegui.org.uk/mantis/view.php?id=192
- Bug Fix: When linking on autotools based systems, ensure we explicitly link with the 'just built' versions of CEGUI libraries; this ensures that we are not inadvertently picking up old installed versions of the same libs.
- Bug Fix: Updated Ogre base application to correctly respond to window resize events and inform the CEGUI renderer of the change.  Part of fixes for: http://www.cegui.org.uk/mantis/view.php?id=187
- Bug Fix: Fixed samples under D3D 8.1 and 9 so that they correctly notify CEGUI when the window size changes.  Part of fixes for: http://www.cegui.org.uk/mantis/view.php?id=187.
- Bug Fix: Under gcc/autotools the various libraries and modules were not linking against CEGUIBase (except on MinGW32).  See: http://www.cegui.org.uk/mantis/view.php?id=196
- Bug Fix: Update Irrlicht sample base application to notify the renderer of the display size - in order that it may react properly to any changes.  (Part of fixes for: http://www.cegui.org.uk/mantis/view.php?id=187).
- Bug Fix: When injecting mouse position change information using the System::injectMousePosition member, the resulting MouseEventArgs structure passed to event handlers always had the positional change delta information set to 0.  See: http://www.cegui.org.uk/mantis/view.php?id=194
- Bug Fix: FrameWindow types had no realistic default minimum size specified, meaning the user could resize these windows to such an extent that they totally disappeared and we no longer usable.  See: http://www.cegui.org.uk/mantis/view.php?id=193
- Bug Fix: Issue with detection and usage of glut library under Msys/MinGW.  See: http://www.cegui.org.uk/mantis/view.php?id=184
- Bug Fix: Can't get correct error string on Win32 platform when dynamic module load failed.  See: http://www.cegui.org.uk/mantis/view.php?id=178
- Bug Fix: Missing winmm library dependency for MinGW32 autotool based builds.  See: http://www.cegui.org.uk/mantis/view.php?id=183

- Modified: Applied ticket #173
- Modified: Renamed Demo4 to TextDemo (in progress).
- Modified: linux (and mingw32) will try with and without the 'lib' prefix when loading dynamic modules.
- Modified: Applied this patch: http://www.cegui.org.uk/mantis/view.php?id=168
- Modified: datafiles are now installed on linux (e.g. /usr/local/share/CEGUI/)
- Modified: Minor change to update a contact address (main purpose of this is actually to test the svn change notification system).
- Modified: RTTI and Loggers - See http://www.cegui.org.uk/phpBB2/viewtopic.php?t=2816
- Modified: Updated samples with new exception code
- Modified: Applied large patches. For details see this thread: http://www.cegui.org.uk/phpBB2/viewtopic.php?t=2766
- Modified: setDefaultXMLParserName now unloads the default dynamic module and loads a new one provided you are not statically linking.
- Modified: tolua++cegui changes in exception handlers.
- Modified: Large Premake updates

- Coding Standards: CEGUI does not use the NULL macro in code.
- Coding Standards: the prefix used for data members on the CEGUI project is d_ and not m_

- Bug Fix: Corona based image codec would not build.
- Bug Fix: Resolve a thousand and one "deprecated conversion from string constant to 'char*'" warnings that spew forth from gcc 4.2.x.
- Bug Fix: Lua 5.1 removes table.setn - update code to use alternate method of ensuring table is indeed empty.
- Bug Fix: The CEGUIDeadException macro was causing the exceptions to be caught by value; this fixes it so they are caught by reference.
- Bug Fix: Exception base class destructor should be public.
- Bug Fix: Minor TextDemo fix - gcc does not like temporary objects passed as arguments for non-const function parameters.
- Bug Fix: Autotool build fix for TextDemo.
- Bug Fix: Small compile fix for VS
- Bug Fix: Groupbox fix (disabled 'ristOnClick')
- Bug Fix: Window::isTopOfZOrder had an incorrectly constructed loop control.  (http://www.cegui.org.uk/mantis/view.php?id=172)
- Bug Fix: PixelAligned macro was incorrect when working with negative values.  (http://www.cegui.org.uk/mantis/view.php?id=167)
- Bug Fix: Listbox and MulticolumnList were not re-sorting the list in resonse to calling handleUpdatedItemData which resulted in an incorrectly ordered list if items had changed in a manner that invalidated the current order (in the simplest case, just by changing an items text). (http://www.cegui.org.uk/mantis/view.php?id=162)
- Bug Fix: The 'selected item' as returned by Combobox would revert to 0 after interaction with the user that did not end with a positive list selection - this is incorrect; any previous selection should be preserved if the user backs out of making a new selection in the list.  NB: A side effect of this fix is a change in the order that some events are fired.  Previously the droplist show/hide event came first (before any selection events), now the show/hide events come after any selection events. (http://www.cegui.org.uk/mantis/view.php?id=164).
- Bug Fix: Slider thumb was not showing up when used within a TabControl.  Actual bug was related to thumb getting initialised with bad data caused by unchecked divide by zero in the Falagard window renderer. (http://www.cegui.org.uk/mantis/view.php?id=145)
- Bug Fix: Invalidating only cached clipped areas for a window was not having the desired effect on child content.  Fix addresses http://www.cegui.org.uk/mantis/view.php?id=165
- Bug Fix: Any window responding to a left mouse button down event would always report the event as 'unhandled' even though it may have taken action based on the event (thus, handling it).  Event is now marked as 'handled' if, but only if, the window has to take action such as activating the window or making a change in the z-order.  (http://www.cegui.org.uk/mantis/view.php?id=136)
- Bug Fix: MultiLineEditbox::onCharacter should only say it handled the event if it really did.  (http://www.cegui.org.uk/mantis/view.php?id=155)
- Bug Fix: Widgets with a push-button-esque behaviour were not behaving correctly as regards to being obscured by a window with mouse pass through enabled.(http://www.cegui.org.uk/mantis/view.php?id=154 and http://www.cegui.org.uk/phpBB2/viewtopic.php?t=2971)
- Bug Fix: We were incorrectly using the clock() function as a timer. (http://www.cegui.org.uk/mantis/view.php?id=153)
- Bug Fix: Certain assign, append, and insert operations in CEGUI::String would illegally operate beyond the length of the object being assigned, appended or inserted. (http://www.cegui.org.uk/mantis/view.php?id=152)
- Bug Fix: Bug where MultiColumnListProperties::MultiColumnListProperties::set was using String::substr incorrectly and accessing chars beyond the end of the string.  This fix is actually a total rewrite that makes the function a lot more robust, and removes a couple of other issues too.  (http://www.cegui.org.uk/mantis/view.php?id=171)
- Bug Fix: Correctly check for dl and pthread libs. (http://www.cegui.org.uk/mantis/view.php?id=143)

    - It is now possible to navigate to the Combobox via keyboard.
    - First available renderer is pre-selected into the dialog.
    - With a single renderer available, it is auto-selected and dialog is not shown.

- Bug Fix: Added another 'special case' to Spinner::getValueFromText to support typing an initial decimal point.
- Bug Fix: Sometimes compound widgets did not get their components layed out properly when adding the widget to it's parent.
- Bug Fix: The way in which properties would set a window to use the DefaultFont was incorrect; it explicitly set it to the name of the current default, as opposed to a 'floating default'.
- Bug Fix: FontDim did not work correctly since re-calculation of the layout was not triggered in response to the font being changed.  Added this code to Window::onFontChanged - although more elegant / selective solutions might be considered later on.
- Bug Fix: Added code so that all windows using default font get notified of a change in the default via the normal channel (Window::onFontChanged).
- Bug Fix: There was an issue regarding auto-repeat of mouse button down events not getting their state reset if the mouse button was released outside of the window getting the auto-repeat events.

- Bug Fix: Calculation of number of glyph pages in Font::setMaxCodepoint was incorrect.
- Bug Fix: When the OpenGL renderer was disabled by ./configure, the SILLY codec was still being built.

- Bug Fix: case of included file in Win32CEGuiRendererSelector.cpp changed ready to support cross-compiling in post 0.5.0 versions.
- Bug Fix: Support was broken in the Samples framework for newer versions of Ogre.
- Bug Fix: The cegui_reldim and cegui_absdim macros were missing the CEGUI namespace qualifier.
- Bug Fix: When a glyph failed to load in FreeTypeFont, although we logged the error we did not work around the issue of the missing glyph image, so a seg fault was generated upon attempted use of those missing images. This addresses the issue by creating dummy images for missing font glyphs which use a zero size. Mantis #0000125.
- Bug Fix: RefCounted would call AddRef when the wrapped pointer and its counter were null.
- Bug Fix: Event::ScopedConnection would call members of BoundSlot using a potentially null RefCounted pointer.

    - Removed use of NULL macro from the library code.
    - Code refactorings to Font class. Removes some instances of repeated code, and makes some methods shorter / cleaner.
    - Split large methods in Scheme into smaller, more managable, chunks.
    - Removed all the System constructor overloads and replaced with a single method.
    - Removed string literals for component widget names which were scattered throughout the widget code.
    - Replaced virtually all member fields holding pointers to component widgets with getter methods (which basically allows those widgets to be replaced without the parent knowing or caring).
    - Refactoring of XML handler to remove huge if/else if/else construct.
    - Refectored large if / else if / else constructs in all non-falagard XML handlers to use a member function for each element type (rather than having all code in one huge function).
    - Event system has been rewritten from scratch.
    - Font system has been rewritten.

- Added "PushedOff" rendering state for button based widgets and MenuItem.
- Added: Ability to rename windows.
- Added: CEGUISamplesConfig.h file to allow configuration of samples framework independently of the main config (saves recompiling everything just to change some sample setting).
- Added: FPS readout to OpenGL base app in the samples framework.
- Added: "PropertyLinkDefinition" element for Falagard system.
- Added: "controlPropery" attribute to SectionSpecififations under falagard to enable renering of section imagery to be controled via a named boolean property.
- Added: mouse pass through feature in Window, to ignore mouse events. Nice for making a DefaultWindow transparent to the mouse regarding picking windows behind it.
- Added: MSVC++ auto-linking for Ogre base app in samples framework.
- Added: grab/restoreTextures in the OpenGL renderer to cache texture image data, and later restore it.
- Added: Abstracted Logger interface to support user created custom loggers. (SF patch #1414121 by zap)
- Added: DefaultLogger implementation (SF patch #1414121 by zap)
- Added: page up/down key functionality to MultiLineEditbox (SF patch #1347376 by Dalfy)

- Added: Text node support to both parser (Xerces and TinyXML)
- Added: AutoWindow tag to xml layouts to fetch a window created by the look'n'feel or the base widget itself.
- Added: Window::isAutoWindow member that returns true if the window has "__auto_" in its name. (a flag is set in the constructor). It's faster than checking the actual string.
- Added: A setting to Window to specify that it should never write XML no matter what if activated. Tooltips get this set by default by System.
- Added: A property ban list to provide a system for mapping which properties should (not) be written to XML. In the respective addProperties member functions checks have been added and some properties are banned if we are an auto window.
- Added: Default resource group support to Xerces for use when loading schema files.

In CVS HEAD the actual Lua function is referenced, but now this will only occur the first time the event is triggered. This means that it's no longer necessary to have a function defined to subscribe it to an event. As long as the function has been created before the event occurs everything will be good Smile
- Modified: Moved subscribeScriptedEvent into ScriptModule to allow more customized script subscription functionality.
- Modified: Made the layout XML handler use subscribeScriptedEvent for Event tags instead of subscribeEvent with ScriptFunctor
- Modified: Removal of "tolua_outside" stuff that was no longer needed.
