## RabbitMQ 3.8.11
|
||
|
|
|
||
|
|
RabbitMQ `3.8.11` is a maintenance release that contains bug fixes.
|
||
|
|
|
||
|
|
This release [**no longer supports** Erlang 21.3](https://groups.google.com/forum/#!topic/rabbitmq-users/v3K5nZNsfwM).
|
||
|
|
|
||
|
|
### Erlang/OTP Compatibility Notes
|
||
|
|
|
||
|
|
This release [requires Erlang 22](https://www.rabbitmq.com/which-erlang.html) or
|
||
|
|
[Erlang 23](http://blog.erlang.org/OTP-23-Highlights/).
|
||
|
|
|
||
|
|
Erlang 21.3 [**is no longer supported**](https://groups.google.com/forum/#!topic/rabbitmq-users/v3K5nZNsfwM).
|
||
|
|
`22.3` or `23.2` releases are recommended.
|
||
|
|
|
||
|
|
[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 `22.3.x`.
|
||
|

|
## Upgrade and Compatibility Notes
|
||
|
|
|
||
|
|
### Upgrade Doc Guides and Change Log
|
||
|
|
|
||
|
|
See [3.8.0 release notes](https://github.com/rabbitmq/rabbitmq-server/releases/tag/v3.8.0) upgrade and
|
||
|
|
compatibility notes first if upgrading from an earlier release series (e.g. `3.7.x`).
|
||
|
|
|
||
|
|
See the [Upgrading guide](https://www.rabbitmq.com/upgrade.html) for general documentation on upgrades and
|
||
|
|
[RabbitMQ change log](https://www.rabbitmq.com/changelog.html) for release notes of other releases.
|
||
|
|
|
||
|
|
### Upgrading to Erlang 22.x or Later Versions
|
||
|
|
|
||
|
|
When upgrading to this release from `3.7.15` or an older version, extra care has to be taken.
|
||
|
|
|
||
|
|
Because older RabbitMQ CLI tools can be incompatible with Erlang 22+ releases,
|
||
|
|
RabbitMQ **must be upgraded at the same time as Erlang**.
|
||
|
|
|
||
|
|
Alternatively the node can be upgraded to `3.7.18` on Erlang 21.3 first,
|
||
|
|
then Erlang 22.x or 23.x, then RabbitMQ to the most recent 3.8.x release.
|
||
|
|
|
||
|
|
