The previously mentioned management plugin is now in a state where it's worth looking at and testing. In order to make this easy, I've made a special once-only binary release just for the management plugin (in future we'll make binary releases of it just like the other plugins). Download all the .ez files from here and install them as described here, then let us know what you think. (Update 2010-09-22: Note that the plugins referenced in this blog post are for version 2.0.0 of RabbitMQ. We've now released 2.1.0 - for this and subsequent versions you can get the management plugin from here).

Some three and a half years after we launched RabbitMQ, we have this week released RabbitMQ 2.0.

This means some big changes.  The most important of these is our new Scalable Storage Engine.  RabbitMQ has always provided persistence for failure recovery.  But now, you can happily push data into Rabbit regardless of how much data is already stored, and you don't need to worry about slow consumers disrupting processing.  As the demands on your application grow, Rabbit can scale with you, in a stable, reliable way.

Before introducing RabbitMQ 2.0, let me reiterate that as Rabbit evolves you can count on the same high level of commitment to you as a customer or end user, regardless of whether you are a large enterprise, or a next-gen start-up, or an open source community.  As always, get in touch if you need help or commercial support.

For a long time the management and monitoring capabilities built into RabbitMQ have consisted of rabbitmqctl. While it's a reasonable tool for management (assuming you like the command line), rabbitmqctl has never been very powerful as a monitoring tool. So we're going to build something better.

Since the beginning, RabbitMQ has implemented the 0-8 version of the AMQP specification. This was the first publicly-available version, but there's been plenty of development since then. In particular, we've wanted to support the 0-9-1 version of AMQP for a while now.

Support for AMQP's basic.reject just landed on default. It's taken this long because we couldn't agree on a single set of semantics that followed the specification, was actually useful, and wasn't too complicated to implement.

And welcome to the all-new RabbitMQ blog!
