Changes between 2.4.0 and 2.5.0

This is a maintenance release with a bug fix and a new feature. All users are encouraged to upgrade to this release.

Note PerfTest termination sequence has slightly changed: it used to terminate quickly without closing AMQP connections when interrupted. It now tries to close AMQP connections and times out after 5 seconds. The timeout can be changed with the --shutdown-timeout command line argument. See the documentation for more information.
