+ New feature added: Task notifications.
+ Optimise Cortex-M4F ports by inlining some critical section macros. + Original ports used a #define to set the path to portmacro.h - that method has been obsolete for years and now all the old definitions have been moved into a separate header files called deprecated_definitions.h. + Cortex-M port now check the active vector bits against 0xff when determining if a function is called from an interrupt - previously only a subset of the bits (0x1f) were checked. + Add in new standard demo/test files TaskNotify.c/h and include the files in the simulator demos. + Update trace recorder code, and some demos to use the new version (more to do). + Introduce uxTaskPriorityGetFromISR(). + Minor typo corrections. + Update MingW simulator demo to match the MSVC simulator demo.
