• changed itervalues() to values() for compatibility with python3.

• Change iteritems() to items() in getInputList. Add test. Fixes #40.

• Fixing conversion from unsupported texcoord. input.

• use 'from PIL import Image' instead of 'import Image'.

Backwards Compatibility Notes

• Python 2.5 is no longer supported. Supported versions are now 2.6, 2.7 and 3.2.

New Features

• Added support for reading the opaque attribute from <transparent> tag.

• Normals and texture coordinate indices are now available in shapes (Triangle and Polygon).

• Library is now compatible with python's built-in ElementTree API instead of requiring lxml. lxml is still recommended.

• Added support for Python 3.2. Supported versions are now 2.6, 2.7 and 3.2.

• Added support for index_of_refraction in <effect>.

• Added optional parameter to Collada that does XML schema validation when saving.

• Automatically corrects broken files that don't have correct xfov, yfov, and aspect ratio in cameras.

Bug Fixes

• Fix the default value for transparency in Effect. Now correctly defaults to 1.0 when opaque mode is A_ONE, and 0.0 when opaque mode is RGB_ZERO.

• Fixed bug where BoundPolylist was not returning the correct length value.

• Removed support for RGB from Effect since it's not valid in the spec. If an RGB is given, a fourth A channel is automatically added as 1.0.

• Made instance_geometry not write an empty bind_material if it's empty since it breaks validation.

• Made saving strip out empty <library_*> tags since it breaks validation.

Backwards Compatibility Notes

• If using the old Camera object, this has been changed to an abstract class with types for PerspectiveCamera and OrthographicCamera

• If using the old Collada.assetInfo dictionary to read asset information, this has been changed to an object. See documentation for more information.

New Features

• Added support for bump maps inside the extra tag of an effect

• Added texbinormal and textangent to triangle sets

• Added a method to generate texture tangents and binormals

• Added detection for double_sided

• Added an optional parameter to specify what filename inside an archive to use when loading from zip

• Added support for loading multiple sets of library_* nodes

• Refactored asset information into a separate module. Fixed #12

• Refactored Camera into PerspectiveCamera and OrthographicCamera, inheriting from Camera

Bug Fixes

• Fixed bug when triangulating a length-0 polylist

• Updated install instructions for OS X and Ubuntu problems

• Changed geometry export to delete any sources in the vertices tag that no longer exist

• Changed library output to not output empty library nodes so validator doesn't complain

• Add same checks in scene loading that was done in library_nodes loading so that if nodes are not found yet while loading, it will keep trying

• Changed the way library_nodes is loaded so that if a referenced node from instance_node is not loaded yet, it will keep trying

• Fixed bug where a triangles xml node would try to set an attribute to None

• Fixed bug in handling joints that influence 0 vertices

• Changed the way instance_node is handled to actually maintain the mapping so it's not lost when saving

• Added setdata function to CImage and made Effect compare only image path

• Fixed a bug when rewriting geometry sources

• Change primitive sources to point to the <vertices> tag when possible since other importers don't like not having a <vertices> tag
