+*** 0.5.0 ***
+- NEW: Binary Mutexes, the new mechanism provides a complete implementation
+ of the "priority inheritance" algorithm as a tool for work around the
+ priority inversion problem.
+ The Mutexes are not meant to replace the Semaphores that are still the best
+ mechanism for synchronization between interrupt handlers and high level
+ code, something Mutexes cannot do.
+ Soon an article will be added to the wiki describing pro and cons of the
+ various mechanisms and the correct use cases.
+- RT Semaphores subsystem removed, the Mutexes implements a better solution
+ for the same problem.
+
*** 0.4.5 ***
- Moved the serial IRQ handlers and VIC vectors initialization inside the
serial drivers. Now the serial-related code is all inside the driver.
