release-notes/3.8.14.md
RabbitMQ 3.8.14 is a maintenance release that restores
Erlang 22.3 compatibility for environments that use direct reply-to.
This release requires Erlang 22.3. Erlang 23 is highly recommended for best forward compatibility with future RabbitMQ versions.
Provisioning Latest Erlang Releases explains
what package repositories and tools can be used to provision a recent version of Erlang 23.x.
See 3.8.0 release notes upgrade and
compatibility notes first if upgrading from an earlier release series (e.g. 3.7.x).
See the Upgrading guide for general documentation on upgrades and RabbitMQ change log for release notes of other releases.
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 23.x, then RabbitMQ to the most recent 3.8.x release.
Any questions about this release, upgrades or RabbitMQ in general are welcome on the RabbitMQ mailing list and RabbitMQ community Slack.
Direct reply-to failed witn an exception on Erlang 22.3. Nodes running on Erlang 23 are not affected.
GitHub issue: #2857
A warnings about async I/O threads was replaced with a similar one about dirty I/O schedulers. This keeps the message up with the settings used in modern Erlang releases.
