RabbitMQ developers have rolled out version 2.0.0 of their open source messaging system today.
All users are encouraged to upgrade.
"This release includes a rewritten message store that pages messages to disk to relieve memory pressure, and support for AMQP 0-9-1," RabbitMQ team member Michael Bridgen said in the announcement. "There are many other more modest additions, such as an implementation of basic.reject, and queue leases."
A complete list of changes, bug fixes and enhancements are listed here.
Source and binary distributions are available here.
