Blender's import function check's the Text datablocks in main for additional modules for importing. However, libloaded scenes were 1) not loading Text datablocks and 2) not letting bpy know about them. Text datablocks are now loaded if a Scene is loaded and bpy can now looking through extra Mains to find additional modules.
========================
The linear and angular thresholds set the speed limit (in m/s) and rotation limit (in rad/s)
under which a rigid body will go to sleep (stop moving) if it stays below the limits for a
time equal or longer than the deactivation time (sleeping is disabled is deactivation time is
set to 0).
These settings help reducing the processing spent on Physics during the game.
Previously they were only accessible from python but not working because of a bug.
Now the python functions are working and the settings are available in the Physics panel
of the World settings when using the Blender Game render engine.
Python API:
import PhysicsConstraints
PhysicsConstraints.setDeactivationLinearTreshold(float)
PhysicsConstraints.setDeactivationAngularTreshold(float)
===============================================
This patch adds a new "Character" BGE physics type which uses Bullet's btKinematicCharacter for simulation instead of full-blown dynamics. It is appropiate for (player-controlled) characters, for which the other physics types often result unexpected results (bouncing off walls, sliding etc.) and for which simple kinematics offers much more precision.
"Character" can be chosen like any other physics type in the "Physics" section of the properties window. Current settings for tweaking are "Step Height" (to make the object automatically climb small steps if it collides with them), "Fall Speed" (the maximum speed that the object can have when falling) and "Jump Speed", which is currently not used.
See http://projects.blender.org/tracker/?func=detail&atid=127&aid=28476&group_id=9
for sample blends and a discussion on the patch: how to use it and what influences the behavior of the character object.
Known problem: there is a crash if the "compound" option is set in the physics panel of the Character object.
Also adds DampedTrackTo to the list of supported constraints in the BGE

Patch developed as part of a project to NF-UBC Nereus Program.
Development time 'sponsored' by the project.

- spelling - turns out we had tessellation spelt wrong all over.
- use \directive for doxy (not @directive)
- remove BLI_sparsemap.h - was from bmesh merge IIRC but entire file commented and not used.
[#30059] Shape Keys is gone in Blender if you use Add Object Actuator in BGE
[#30024] Segmentation fault after addObject when using shape keys
[#28683] segfault in shapekey conversion code when running a game (YF, level home) twice
The crash occurred when an action actuator was attached to a non-armature object because objects that aren't armatures do not have pose data. A NotImplementedError is now raised if someone tries to access any of the following with an action actuator attached to a non-armature object:
BL_ActionActuator.channelNames
BL_ActionActuator.getChannel()
BL_ActionActuator.setChannel()
