3.7.14

RabbitMQ 3.7.14

RabbitMQ 3.7.14 is a maintenance release. It focuses on bug fixes and minor usability improvements. This release requires Erlang/OTP 20.3 or later.

Erlang/OTP Compatibility Notes

Per the new Erlang version support policy in effect starting with January 2019, this release no longer supports Erlang/OTP 19.3. 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 20.3.x and 21.x.

Compatibility Notes

Minimum Required Erlang Version

This release requires Erlang/OTP 20.3 or later.

Upgrading to Erlang 21.x

When upgrading to this release and upgrading Erlang to 21.x 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, RabbitMQ must be upgraded before Erlang.
