the extra capability of making it possible for Observers to assume ownership of a object that would otherwsie be deleted.
Added a thread safe ref_ptr<T> observer_ptr<T>::lock() method for robust access to an observed object. This
makes observer_ptr<> more equivilant to boosts weak_ptr.
Introduced the OSG_NOTIFY_DISABLE Cmake variable + include/osg/Config #define to control whether the OpenSceneGraph build
should disable the notification system completely. By setting OSG_NOTIFY_DISABLE to ON in CMake and then rebuilding the
the OSG you can get a slightly smaller (~1%) and more slightly efficient library which can be good for shipping applications,
but with downside of reduced ability to detect runtime problems and their causes.
OSGDB_EXPORT macro to RegisterCompressorProxy, and modified the
findCompressor() method to look for custom compressors in libraries
such like osgdb_compressor_name.so, which was described in the wiki
page chapter 2.4."
1. Rewrite the reading/writing exception handlers to work like the ive
plugin exceptions.
2. Write a header writing/checking function in ReaderWriterOSG2.cpp,
which may help decide if the stream is ascii or binary. The
readInputIterator() function will return null pointer if the input
file is nither osgb nor osgt format, which indicates that the old .osg
format could be used here, in case we've merged the two plugins
together.
3. Add a new ForceReadingImage option in the InputStream, which will
allocate an empty image object with the filename if specifed external
image file is missed. It may be useful for format converting in some
cases.
4. Add new osgParticle wrappers, as well as some modification to the
osgParticle headers, for instance, change isEnabled() to getEnabled().
5. Some fixes to the osg serialization wrappers."
Bone now inherit from MatrixTransform. It simplify a lot the update of
Bone matrix. It helps to have the bone system more generic. eg it's now
possible to have animation data with precomputed bind matrix. The other
benefit, is now the collada plugin will be able to use osgAnimation to
display skinned mesh. Michael Plating did a great work to improve this
aspect, he is working on the collada plugin and should be able to submit
a new version soon.
The RigGeometry has been refactored so now it works when you save and
reload RigGeometry because the source is not touched anymore. The
benefit with this update is that it should be now possible to use a
MorphGeometry as source for a RigGeometry.
The bad news is that the format has changed, so i have rebuild osg-data
related to osgAnimation data, updated the blender exporter to export to
the new format.
The fbx plugin could be touched about this commit, i dont compile it so
i can't give more information about it.
The bvh plugin has been updated by Wang rui so this one is fixed with
the new code of osgAnimation.
The examples has been updated to work with the new code too...
The example osg-data/example.osg should be remove, it's an old example
that does not work.
For people using blender the blender exporter up to date is here:
http://hg.plopbyte.net/osgexport2/
it will be merge to http://hg.plopbyte.net/osgexport/ as soon as the
modification will be push in the trunk.

I found very useful to have a control whether osgView::setCameraManipulator does or does not reset camera to home position.
I extended method signature as follows:
void setCameraManipulator(osgGA::MatrixManipulator* manipulator, bool resetPosition = true);
keeping the current usage intact (default parameter), while enabling user to disable the position reset. That can be useful in the situation when manipulator position was already loaded, for example from a file (user specification), or defined any other way, while we do not want to be reset to home position. Other usability is usage of two manipulators in a modeling program (orbiting around the model, walking on the model) and changing between them while we want to preserve the position of a camera in the change. Games may benefit from it as well when we change from user-defined helicopter manipulator to soldier manipulator because the user escaped the helicopter. The camera will change manipulator but the position is expected to be kept in the transition (provided that user makes the state transition between the two manipulators himself).

From Robert Osfield, I didn't merge the change of parameter type of IntersectKdTree::intersect() as the internal maths is all done in Vec3s. Keeping Vec3 here hasn't effected the test results.
destruction of RequestQueue to remove any pointers held in DatabaseRequest attached to the scene graph, and to
prevent their subsequent use in cases where the scene graph is attached to a new DatabasePager.
to the osgDB::Registry. Added a osgDB::Registry::getObjectWrapperManager() for access of this object wrapper manager. This
change centralises the singleton management in osgDB.
Merged the osgDB::GlobalLookUpTable functionality into ObjectWrapperManger to keep down the number of singletons in use.
From Robert Osfield, refactor of Wang Rui's original osg2 into 3 parts - parts placed into osgDB, the ReaderWriter placed into src/osg/Plugin/osg and wrappers into src/osgWrappers/serializers/osg
