RabbitMQ 3.7.18-rc.1
Pre-releaseRabbitMQ 3.7.18-rc.1
RabbitMQ 3.7.18-rc.1 is a preview of a maintenance release. It focuses on bug fixes and internal
API changes that refine the common plugin API with the upcoming 3.8.0 version.
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
This release contains a breaking change to the plugin API around queue state access introduced in 3.7.17.
Plugins that do not use that API revision are not affected. All plugins that ship with RabbitMQ have been updated
as necessary.
This revision was necessary to maintain a single API with the upcoming 3.8.0 release.
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.
