RabbitMQ 3.7.17-beta.1

RabbitMQ 3.7.17

RabbitMQ 3.7.17-beta.1 is a preview of a maintenance release. It focuses on bug fixes and minor usability improvements.

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 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.

Changes

Core Server

Enhancements

• amqqueue module and the feature flag subsystem were backported from 3.8. This makes it possible
  for plugin developers to target both 3.7.x and 3.8.x release series.

  Note that this only backports the API. There are no feature flags to enable in 3.7.17.
  No 3.8-specific features that must be enabled via feature flags were backported and there are no
  plans to do it in later 3.7.x releases.
