-
-FIXES/HOUSEKEEPING:
-    - Hundreds of bugfixes in all parts of the library
-    - CMake is now the primary build system

-
-
-3.0 (2012-07-07)
-
-FEATURES:
-   - new export interface similar to the import API.
-   - Supported export formats: Collada, OBJ, PLY and STL

-   - new postprocessing steps: Debone
-   - vastly improved IFC (Industry Foundation Classes) support

-   - renamed headers, export interface, C API properties and meta data
-     prevent compatibility with code written for 2.0, but in
-     most cases these can be easily resolved
-   - Note: 3.0 is not binary compatible with 2.0
-
-
-
-
-2.0 (2010-11-21)
-
-FEATURES:
-   - Add support for static Blender (*.blend) scenes
-   - Add support for Q3BSP scenes
-   - Add a windows-based OpenGL sample featuring texturing & basic materials
-   - Add an experimental progress feedback interface.
-   - Vastly improved performance (up to 500%, depending on mesh size and
-     spatial structure) in some expensive postprocessing steps
-   - AssimpView now uses a reworked layout which leaves more space
-     to the scene hierarchy window
-
-   - Add C# bindings ('Assimp.NET')
-   - Keep BSD-licensed and otherwise free test files in separate
-     folders (./test/models and ./test/models-nonbsd).
-
-FIXES:
-   - Many Collada bugfixes, improve fault tolerance
-   - Fix possible crashes in the Obj loader
-   - Improve the Ogre XML loader
-   - OpenGL-sample now works with MinGW
-   - Fix Importer::FindLoader failing on uppercase file extensions
-   - Fix flawed path handling when locating external files
-   - Limit the maximum number of vertices, faces, face indices and
-     weights that Assimp is able to handle. This is to avoid
-     crashes due to overflowing counters.
-
-   - Updated XCode project files
-   - Further CMAKE build improvements
-
-
-API CHANGES:
-   - Add data structures for vertex-based animations (These are not
-     currently used, however ...)
-   - Some Assimp::Importer methods are const now.
-
-
-
-
-
-1.1 (2010-04-17)
-This is the list of relevant changes from the 1.0 (r412) release to 1.1 (r700).
-
-FEATURES:
-  - Vastly improved Collada support
-  - Add MS3D (Milkshape 3D) support
-  - Add support for Ogre XML static meshes
-  - Add experimental COB (TrueSpace) support
-  - Automatic test suite to quickly locate regressions
-  - D bindings (`dAssimp`)
-  - Python 2.n bindings (`PyAssimp`)
-  - Add basic support for Unicode input files (utf8, utf16 and utf32)
-  - Add further utilities to the `assimp` tool (xml/binary dumps, quick file stats)
-  - Switch to a CMAKE-based build system including an install target for unix'es
-  - Automatic evaluation of subdivision surfaces for some formats.
-  - Add `Importer::ReadFileFromMemory` and the corresponding C-API `aiReadFileFromMemory`
-  - Expose further math utilities via the C-API (i.e. `aiMultiplyMatrix4`)
-
-  - Move noboost files away from the public include directory
-  - Many, many bugfixes and improvements in existing loaders and postprocessing steps
-  - Documentation improved and clarified in many places.
-  - Add a sample on using Assimp in conjunction with OpenGL
-
-  - Distribution/packaging: comfortable SDK installer for Windows
-  - Distribution/packaging: improved release packages for other architectures
-
-CRITICAL FIXES:
-  - Resolve problems with clashing heap managers, STL ABIs and runtime libraries (win32)
-  - Fix automatic detection of file type if no file extension is given
-  - Improved exception safety and robustness, prevent leaking of exceptions through the C interface
-  - Fix possible heap corruption due to material properties pulled in incorrectly
-  - Avoid leaking in certain error scenarios
-  - Fix 64 bit compatibility problems in some loaders (i.e. MDL)
-
-BREAKING API CHANGES:
-  - None -
-
-MINOR API BEHAVIOUR CHANGES:
- - Change quaternion orientation to suit to the more common convention (-w).
- - aiString is utf8 now. Not yet consistent, however.
