   * chEvtWaitAll()      - Wait with AND condition.
   * chEvtDispatch()     - Invokes the event handlers associated to a mask.
   * chEvtPend()         - Quickly self-pends some events.
+  * chEvtRegisterMask() - Registers a set of flags on a single source.
   All the "wait"-type APIs have a timeout-capable variant.
 - CHANGE: The old chEvtWait() and chEvtWaitTimeout() APIs are now deprecated
   and will be removed in version 1.0.0.
 - CHANGE: Modified chDbgAssert() to syntax check the condition even when the
   CH_USE_DEBUG is disabled, it produces no code but allows to check the
   optional code without have to compile twice.
+- FIX: Fixed a warning generated by the chEvtIsListening() macro.
 - Added a new benchmark to the test suite (timers set/reset performance).
 - Renamed the macro fifo_init() to queue_init() because it is used to init
   both FIFO queues and priority queues.
