* Support for Windows 64 bit build has been added, allowing windows programmers to take advantage of the scalability that Linux, IRIX, Solaris, FreeBSD and OSX prorgramers have enjoyed with the OpenSceneGraph for years. * Support for Windows 64 bit build has been added, allowing windows programmers to take advantage of the scalability that Linux, IRIX, Solaris, FreeBSD and OSX prorgramers have enjoyed with the OpenSceneGraph for years.

* New COLLADA plugin that supports both the reading and writing of COLLADA 1.4 .dae files. COLLADA is the new industry standard data asset exchange format that is now supported by a range of 3d modelling packages and provides a unified art path route to and from the OpenSceneGraph. * COLLADA plugin with support has been added for both the reading and writing of COLLADA 1.4 .dae files.

* Processor affinity support added allow application to lock cull-draw and database processes to specific processors, thereby avoiding cache coherancy problems associated with processes moving from processor to processor. * Processor affinity support added allow application to lock cull-draw and database processes to specific processors, thereby avoiding cache coherancy problems associated with processes moving from processor to processor.
* A Texture Atlas builder has been added to the database optimization classes, allowing either manual or automated setting up of texture atlas. Using texture atlas can improve performance by reducing the number of state changes required to render a scene, and by allowing databases to batched in large groups of geometry, in a form that better suits modern graphics arhitectures. * A Texture Atlas builder has been added to the database optimization classes, allowing either manual or automated setting up of texture atlas.

* GPU timing stats have been added to the viewer class, provided the time taken to process allow drawing operations down on the GPU for the previous frame. Coupled with the existing timing of CPU update, cull and draw dispatch the stats reporting now provides the end user with a clearer idea of whether their application is CPU or GPU limited and server as a better guide to performance optimization work. * GPU timing stats have been added to the viewer class, provided the time taken to process allow drawing operations down on the GPU for the previous frame.
