+ * new feature: SB-EXT:ATOMIC-INCF allows atomic incrementation of
+ appropriately typed structure slots without locking.
+ * new feature: SB-EXT:CALL-WITH-TIMING provides access to timing
+ information like those gathered by TIME using a programming-friendly
+ interface.
+ * new feature: TIME reports time taken even if the form performs a
+ non-local transfer of control.
+ * enhancement: reduced conservativism on GENCGC platforms: on
+ average 45% less pages pinned (measured from SBCL self build).
+ * bug fix: SB-EXT:COMPARE-AND-SWAP on SYMBOL-VALUE can no longer
+ mutate constant symbols or violate declaimed type of the symbol.
+ * bug fix: SB-THREAD:SIGNAL-SEMAPHORE could fail to wakeup threads
+ sleeping on the semaphore in heavily contested semaphores.
+ * bug fix: semaphores and condition variables were not interrupt
+ safe.
+ * bug fix: SB-THREAD:CONDITION-WAIT doesn't allow waits on mutexes
+ owned by other threads anymore.
