+  * new feature: SB-EXT:ATOMIC-INCF allows atomic incrementation of
+    appropriately typed structure slots without locking.
+  * 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.
