- FIX: Error in MAC driver (bug 3179783)(backported to 2.2.1).
- FIX: Fixed wrong serial driver macros (bug 3173336)(backported to 2.2.1).
+- NEW: Inproved preemption implementation for the Cortex-M0, now it uses
+ the NMI vector in order to restore the original context. The change makes
+ IRQ handling faster and also saves some RAM/ROM space (backported to 2.2.3).
- NEW: Added "IRQ STORM" long duration tests for the STM32 and LPC11xx. The
test demonstrates the system stability in a thread-intensive, progressively
CPU-saturating, IRQ-intensive long duration test.
