=== posix_mq 1.0.0 - kinder, gentler message queues / 2011-03-01 09:17 UTC

  There is one backwards-incompatible API change:

    POSIX_MQ#send returns +true+ on success instead of +nil+
    for consistency with POSIX_MQ#trysend.

  This release adds the POSIX_MQ#trysend, POSIX_MQ#tryreceive and
  POSIX_MQ#tryshift interfaces to avoid exceptions on common
  EAGAIN errors for users of non-blocking queues.

  Bugfixes: non-blocking behavior changes to a shared descriptor
  in a different process are reflected immediately in the child
  (this won't fix race conditions in your code, however).
  Minor bugfixes for posix-mq-rb(1) and quieted warnings for
  1.9.3dev.
