## 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**](https://www.rabbitmq.com/which-erlang.html) 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**](https://groups.google.com/d/msg/rabbitmq-users/G4UJ9zbIYHs/qCeyjkjyCQAJ).
|
|
Make sure a [supported Erlang version](https://www.rabbitmq.com/which-erlang.html) is used before upgrading.
|
|
|
|
[Provisioning Latest Erlang Releases](https://www.rabbitmq.com/which-erlang.html#erlang-repositories) 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**.
|
|
|
|
#### Upgrade Doc Guides and Change Log

|
|
See [3.7.0 release notes](https://github.com/rabbitmq/rabbitmq-server/releases/tag/v3.7.0) upgrade and compatibility notes if upgrading from an earlier release.
