CHANGELOG
----------------------------------------------------------------------
3.1.1 (2014-06-15)
FEATURES:
- Support for FBX 2013 and newer, binary and ASCII (this is partly
work from Google Summer of Code 2012)
- Support for OGRE binary mesh and skeleton format
- Updated BLEND support for newer Blender versions
- Support for arbitrary meta data, used to hold FBX and DAE metadata
- OBJ Export now produces smaller files
- Meshes can now have names, this is supported by the major importers
- Improved IFC geometry generation
- M3 support has been removed
FIXES/HOUSEKEEPING:
- Hundreds of bugfixes in all parts of the library
- CMake is now the primary build system
API COMPATIBILITY:
- 3.1.1 is not binary compatible to 3.0 due to aiNode::mMetaData
and aiMesh::mName
- Export interface has been cleaned up and unified
- Other than that no relevant changes
3.0 (2012-07-07)

Open Asset Import Library (assimp)
========
Open Asset Import Library is a Open Source library designed to load various __3d file formats and convert them into a shared, in-memory format__. It supports more than __30 file formats__ for import and a growing selection of file formats for export. Additionally, assimp features various __post processing tools__ to refine the imported data: _normals and tangent space generation, triangulation, vertex cache locality optimization, removal of degenerate primitives and duplicate vertices, sorting by primitive type, merging of redundant materials_ and many more.
Open Asset Import Library is a Open Source library designed to load various __3d file formats and convert them into a shared, in-memory format__. It supports more than __40 file formats__ for import and a growing selection of file formats for export. Additionally, assimp features various __post processing tools__ to refine the imported data: _normals and tangent space generation, triangulation, vertex cache locality optimization, removal of degenerate primitives and duplicate vertices, sorting by primitive type, merging of redundant materials_ and many more.
This is the development trunk of assimp containing the latest features and bugfixes. For productive use though, we recommend one of the stable releases available from [assimp.sf.net](http://assimp.sf.net) or from *nix package repositories. According to [Travis-CI] (https://travis-ci.org/), the current build status of the trunk is [![Build Status](https://travis-ci.org/assimp/assimp.png)](https://travis-ci.org/assimp/assimp)
