RabbitMQ 3.7.8-rc.1

RabbitMQ 3.7.8 RC1

RabbitMQ 3.7.8 a release candidate of a maintenance release. It focuses on bug fixes and
further improves Erlang/OTP 21 compatibility.

Upgrades and Compatibility

This release has no known incompatibilities with earlier 3.7.x releases.

Upgrading to Erlang 21.0

When upgrading to this release and upgrading Erlang to 21.0 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.

Documentation Guides and Change Log

See 3.7.0 release notes upgrade and
compatibility notes if upgrading from an earlier release.

See the Upgrading guide for general documentation on upgrades and
