Hi all -- I've just tagged 2.8.5 RC1 and would like to request your help in testing. You can check out the release candidate from here:

http://www.openscenegraph.org/svn/osg/OpenSceneGraph/tags/OpenSceneGraph-2.8.5-rc1

All features are in place at this time, with the one exception of the 3DS plugin backport. Assuming that work is complete soon, and there is sufficient testing, we should be able to release in the very near future.

Features in 2.8.5:

 * Uniform performance enhancement.
r11952, Michael Plating's performance enhancement for large numbers of uniforms, which effectively eliminates the std::map<std::string> lookup.
     r11998, Wojciech Lewandowski's backwards compatibility fix for 11952.
     r12074, Chris Hanson's backwards compatibility fix for 11952.

 * Support for Texture2DMultisample
     r11218, changes to Extensions.
     r11229, fix warnings.
     r11365, 2D multisample support.

 * Added new "OutputRelativeTextures" dot OSG plugin export option (not on 
trunk).

 * Enhancements for OcclusionQueryNode.
     r11760 (plus r11472 for OQN.cpp only).
     Support for RTT Camera (not on trunk).

 * osgconv "--use-world-frame" option.

 * NOTIFY_WARN (and friends) macros to ease backporting.
     OSG_NOTIFY_DISABLED CMake variable.

 * FLT plugin update.
A complete backport of the trunk FLT plugin (as if May 4 2010) to the 2.8 branch.
     Includes export fixes for multitexture.
     Includes osgSim MultiSwitch changes in r11971.

 * PNM plugin enhancements:
     r12220, adds support for reading and writing images using streams.
Bug fixes for reading 8-bit and 16-bit images, including loading the images upside-down.

 * Fix issue with linking apps to libdl on Linux systems.

 * osgText fix (r11768) to improve text appearance.

 * Updated osgWrappers for all API changes.

 * Bump version# 2.8.5, SO# 74.


Thanks for your help!
