*****************************************************************************
+*** 0.5.3 ***
+- Removed the chMsgSendTimeout() API, it was conceptually flawed because
+ after sending a message, the sender *has* to wait for the answer or
+ the next sender in queue would receive it instead (the messages server has
+ no way to know that the sender is gone because a timeout).
+ A workaround would make the messages subsystem much heavier and this is
+ not desiderable.
+- Removed the test case for chMsgSendTimeout() from the test suite.
+- Space saved by reorganizing the timeout code into a single scheduler
+ function.
+- The API chThdSleepUntil() become a macro saving some more code space.
+- Because all the above changes the kernel code (ARM) is over 600 bytes
+ smaller.
+
*** 0.5.2 ***
- Fixed a small problem in the main header file ch.h.
- Small reordering in the fields of the Thread structure in order to optimize
