release-notes/3.7.19.md
RabbitMQ 3.7.19 is a maintenance release that focuses on bug fixes.
RabbitMQ 3.7.x series is supported through March 2020.
Per the new Erlang version support policy in effect starting with January 2019, this release no longer supports Erlang/OTP 20.3. Make sure a supported Erlang version is used before upgrading.
Provisioning Latest Erlang Releases explains
what package repositories and tools can be used to provision latest patch versions of Erlang 21.3.x and 22.x.
When upgrading to this release and upgrading Erlang to 21.x or later at the same time, extra care has to be taken. Since CLI tools from RabbitMQ releases older than 3.7.7 will fail on Erlang 21 or later, RabbitMQ must be upgraded before Erlang.
See 3.7.0 release notes upgrade and compatibility notes first if upgrading from an earlier release.
See the Upgrading guide for general documentation on upgrades and RabbitMQ change log for release notes of other releases.
Any questions about this release, upgrades or RabbitMQ in general are welcome on the RabbitMQ mailing list.
