RabbitMQ 3.7.19

RabbitMQ 3.7.19 is a maintenance release that focuses on bug fixes. RabbitMQ 3.7.x series is supported through March 2020.

Erlang/OTP Compatibility Notes

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.

Compatibility Notes

Upgrading to Erlang 21.x or Later Versions

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.

Upgrade Doc Guides and Change Log

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.
