*** 0.4.4 ***
+- Fixed a very important bug in the preemption ARM code, important enough to
+ make this update *mandatory*.
+ Note: This is not a kernel bug but something specific with the ARM port, the
+ other ports are not affected.
- Fixed a nasty bug in the pure THUMB mode threads trampoline code (chcore2.s,
threadstart), it failed on THUMB threads returning with a "bx" instruction.
The bug did not affect ARM mode or THUMB with interworking mode.
+ Note: This is not a kernel bug but something specific with the ARM port, the
+ other ports are not affected.
- Fixed a bug in chIQGetTimeout(), interrupts were not re-enabled when exiting
the function because a timeout. The problem affected that API only.
- Fixed a potential problem in chSysInit(), it should not affect any past
