  - Fixed usage of SIrrCreationParameters struct, which dind't have copy constructor and assignment operator anymore, since the Irrlicht version string was made const.

+ - New glext.h (version 41) and glxext.h (version 20) supporting OpenGL 3.0
 
  - Added support for read-only locking of textures. Can speed up those calls.

  - Fixed a performance bug in ISceneNode constructor reported by izhbq412
 
+ - Win32 device now makes the cursor invisible immediately when setVisible(false) is called.

+ - Command line tool for mesh conversion added.

  - Added volume light scene node
 
  - .obj files now won't duplicate vertices unnecessarily. This allows recalculation of smooth normals and other things, and is also faster when rendering. The loading is a little slower now.

   - Windows Mobile 6 SDK

- - b3d meshes now always contain proper normals. Also some other bugs fixed.
+ - Added checks to avoid buffer overrun in b3d loader. Enabled normals calculation in all cases, previously it was not done for lightmapped meshes.
+   Fixed transparency support. Added mipmap creation flag support which might disable mipmap creation too often. Should be checked.
 
  - Burningvideo: MipMap Selection repaired

- - The d3d textures don't keep the initial IImage copied, but use the texture data to recover.
+ - D3D drivers now releases the IImage member from initialization, thus freeing lots of memory. The image is accessible via the driver anyway.
 
  - SDL device character handling enhanced.

    - Fixed a bug in CGUISpriteBank which caused a crash when a non-looping animated sprite reached the end of its animation.
    - Modal screens no longer flash invisible children when rejecting a focus change.
    - Finally added StarSonata patch with table element and TabControl additions. Table is based on MultiColor listbox by Acki, and has loads of changes by CuteAlien.
