BGE bug #17491 fixed: BGE, Dupli instance with different scale, massive slowdown.
...
The root cause of this bug is the fact that Bullet shapes
are shared between duplicated game objects. As the physics
object scale is stored in the shape, all duplicas must
have the same scale otherwise the physics representation
is incorrect.
This fix introduces a mechanism to duplicate shapes at
runtime so that Bullet shapes are not shared anymore.
The drawback is an increased memory consuption.
A reference count mechanism will be introduced in a
later revision to keep Bullet shape shared between
duplicas that have the same scale.

BGE fix bug #17430 : BGE Collide/Touch Sensor interfearing with other unrelated sensor states. The bug was introduced in the recent logic optimization patch. It only affects collision and touch sensors. The bug is fixed by keeping track of registration count.

BGE patch: Optimization of bullet adaptation layer - part 1.
...
First batch of optimizaton of the bullet adaptation layer in the BGE.
- remove circular motion state update.
- optimization of physic adaptation layer for bullet: bypass
unecessary conversion of rotation matrix to quaternion and back.
- remove double updates during object replication.

BGE bug fix (for 2.47): setParent() fix, third part: set mass to 0 when parenting. Allow loc/scale/orientation change on child object with physic controller.

All platforms/build systems: either upgrade to use extern/bullet2, or disable the game engine until the build is fixed.

-added basic support for GameActuator 'load game', relative paths were broken, just load file into memory and load blend from memory.
...
-near sensor support
- python binding for PhysicsConstraints.setNumTimeSubSteps (dividing the physics timestep to tradeoff quality for performance)

- Added support for kinematic objects (interaction between rigidbodies), deriving linear/angular velocity from previous transform/current transform and deltatime.
...
- Made another attempt to migrate from Sumo to Bullet: import of older files automatically switch to Bullet, but you can override it, and save the file in 2.42 version. then it stays Sumo physics.

Fixed several bugs: python refcounting related and Bullet related (basic add/remove object support, bounding volume hierarchy). Added a few files, updated the Bullet scons. Vc6/7 Bullet projectfiles need to add a couple of files: 'Bullet/CollisionShapes/BvhTriangleMeshShape.cpp',
...
'Bullet/CollisionShapes/ConvexTriangleCallback.cpp',
'Bullet/CollisionShapes/EmptyShape.cpp',
'Bullet/CollisionShapes/OptimizedBvh.cpp',
'Bullet/CollisionShapes/TriangleCallback.cpp',
'Bullet/CollisionShapes/TriangleIndexVertexArray.cpp',
'Bullet/NarrowPhaseCollision/ManifoldContactAddResult.cpp'.
Sorry, no armatures fix yet.

added raycast support for bullet (no triangle-mesh support, soon)
added python methods for 'getHitObject', getRayDirection, getHitPosition and getHitNormal for mouse over sensor,
which makes it easy for a shootout.blend demo :)
