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.

Better fix for BGE bug #7892 : dRot is reversed on dynamic objects. Make sure that graphic, Bullet and Sumo(deprecated) objects rotate the same way. This fix reverses the rotation of non-dynamic objects compared to 2.45: you will need to change the sign of dRot in 2.45 games for them to work correctly in 2.46

BGE crash when using angV & linV actuator on static objects
...
The error was causing by the KINEMATIC flag not set automatically when the linear or angular velocity was set on static objects. Note that these actuators still won't work on static objects: the crash is fixed but not the actuator; linV and angV only work on dynamic objects. Fixing the linV and angV actuators on static object requires a bit more reflexion. For the time being, use dRot and dLoc on static objects.
Cleaned the code a bit: added systematic check on the physic controller presence before taking action.
