RabbitMQ 3.0 was recently released with STOMP 1.2 support, new plugins for Web-STOMP and MQTT, several performance improvements and more.
Some of the interesting features introduced in this version -

- Plugins for Web-STOMP (to access from browser over WebSockets, with SockJS as fallback) and MQTT (implements MQTT 3.1)
- Simpler commands for clustering
- Policy-based, faster mirroring
- Dynamic Federation
- New, simpler clustering commands
- Per-message TTL
- Memory Use statistics
You can have a look at entire list of changes along with bug fixes and performance enhancements in the release notes. Some of these are breaking changes as explained in the RabbitMQ blog – the team also describes how to handle them when planning an upgrade.
