+changes relative to sbcl-1.0.37:
+  * INCOMPATIBLE CHANGE: Thread names are now restricted to SIMPLE-STRINGs
+    like for any other thread-related datastructure, MUTEX, etc. (lp#547095)
+  * DEPRECATION: the SB-QUEUE contrib was merged into the SB-CONCURRENCY
+    contrib module. New code should depend on SB-CONCURRENCY, not SB-QUEUE.
+  * DEPRECATION: SB-THEAD:GET-MUTEX was deprecated in favor of
+    SB-THREAD:GRAB-MUTEX.
   * new contrib: SB-CONCURRENCY is a new contrib; it's supposed to contain
     additional data structures and tools for concurrent programming; at the
     moment it contains a lock-free queue, and a lock-free mailbox
     implementation.
+  * new feature: added SB-THREAD:GRAB-MUTEX; it's like the now deprecated
