+== 0.5.0 / 2011-03-3
+ * Changed the constructor for the ZM::Reactor class. It now takes
+ an optional third hash argument. One of the keys that it uses
+ is :zeromq_context. This allows a user to create a master 0mq
+ context and share it with multiple reactors. The point of that is
+ to allow the use of the :inproc transport. That transport is
+ somewhat misnamed since it only allows "inprocess" communication
+ between sockets created by the same context. I needed :inproc to
+ work around a 0mq memory leak (still unfixed) and discovered this
+ issue.
+ A second key is :log_transport which is used by the logging
+ facility.
+ In the future, the first two arguments to ZM::Reactor will likely
+ be rolled into the hash argument. That will be a backwards-
+ incompatible change, so I'm hoping folks read these notes and
+ start preparing.
+ * Many fixes to ZM::Timers. Cancellation is more intelligent about
+ matching timers. Inspection of timers also provides better detail
+ about their contents. Lastly, expired timer removal is much clearer
+ in how it functions *and* it is faster by an order of magnitude.
+ (Note: Array#shift is *way faster* than Array#delete_at(0)).
+ * Timer expiration has changed. Originally, timers fired only when
+ the current time was *greater than* its firing time. Now timers
+ fire when the current time is *greater than or equal to* its firing
+ time.
+ * Modified how arguments are passed to the Forwarder and Queue
+ devices.
+ * Devices now default to a ZMQ::LINGER of 0 (drop messages
+ immediately upon socket close) and a ZMQ::HWM of 1 (only allow
+ 1 outstanding message between senders and receivers). These
+ parameters can be modified using the new argument hash.
+ * ZM::Address now supports the :inproc transport.
+ * Fixed a memory leak where a message was not released when an
+ internal recv operation returned EAGAIN. The code was leaking an
+ empty ZMQ::Message every time.
+ * Added a facility for logging. When a Reactor is instantiated a
+ user may pass in a transport string that indicates where the
+ reactor may *connect* and publish log messages. Part of the
+ contract is that this transport already has a listener bound
+ to it before the connection is attempted (e.g. for inproc
+ transports). If inproc is used, then the user also needs to
+ pass in the shared context via :zeromq_context.
+ * Fixed a bug in Socket#send_messages where EAGAIN was not always
+ properly detected and bubbled up to its caller.
+ * Refactored socket deletion. Hopefully it is easier to understand.
