RabbitMQ
Server AppRabbitMQ 4.3 is the newest actively maintained release, currently at patch 4.3.5. 5 of 18 tracked cycles remain supported. The next cycle scheduled to reach end-of-life is 3.13, on September 17, 2024.
Support pattern
How RabbitMQ has behaved across the cycles tracked here, rather than what its policy documents state. Useful for judging how much runway a version is likely to have before you commit to it.
Support windows are getting shorter: the most recent cycles run about 4 months less than the earlier ones.
Computed from release and end-of-life dates tracked for RabbitMQ. Medians are used rather than averages so one unusually short or long release does not skew the figure. Cycles with no recorded end-of-life date are excluded from the support window.
How RabbitMQ versioning, EOL & security support work
RabbitMQ ships numbered release series with patch releases within each series. Rather than one fixed support-length rule for every series, RabbitMQ's release-information page tracks each series' status directly: fully supported, still inside its support window, or no longer listed and therefore unsupported. Some series are additionally designated LTS (long-term support) candidates, which changes how long they stay covered and by whom.
RabbitMQ vulnerability reports are handled through GitHub Security Advisories on the rabbitmq-server repository or by email. The team investigates disclosures affecting a recent version in a currently supported series and requests a CVE as part of the advisory. Because only currently supported series are investigated and patched, a deployment on an unsupported series will not receive a fix even for a newly disclosed, actively exploited vulnerability.
