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 + GET-MUTEX but takes &key rather than &optional parameters. Also added + :TIMEOUT argument to GRAB-MUTEX on non-sb-lutex platforms like Linux and + BSD. + * new feature: added SB-THREAD:TRY-SEMAPHORE, a non-blocking variant of + SB-THREAD:WAIT-ON-SEMAPHORE. + * new feature: SB-EXT:ATOMIC-DECF has been added as a companion to + SB-EXT:ATOMIC-INCF. + * new feature: a CANCEL-DEADLINE is associated with DEADLINE-TIMEOUT + conditions to defer the deadline for forever. + * enhancement: *STANDARD-OUTPUT*, *STANDARD-INPUT*, and *ERROR-OUTPUT* are + now bivalent. + * enhancement: errors from NO-APPLICABLE-METHOD and + NO-PRIMARY-METHOD now have a RETRY restart available to retry the + generic function call. + * enhancement: SB-BSD-SOCKET improvements + ** sockets and socket streams now have a more informative printed + representation based on the corresponding SOCKET-NAME and + SOCKET-PEERNAME. + ** SOCKET-MAKE-STREAM once more supports the :AUTO-CLOSE option. + (lp#540413) + * improvements to the instrumenting profiler + ** new feature: report per-function GC overhead.
