release-notes/3.8.16.md
RabbitMQ 3.8.16 is a maintenance release.
It reintroduces rabbitmq_peer_discovery_aws plugin that was unintentionally removed
from 3.8.15 due to release pipeline changes.
This is the first release to drop support for Erlang 22.3 and introduce support for the upcoming Erlang 24 release.
This release is distributed via GitHub, Cloudsmith, and PackageCloud.
This is the first release to require Erlang 23.2 or later and support upcoming Erlang 24.
Provisioning Latest Erlang Releases explains
what package repositories and tools can be used to provision a recent version of Erlang 23.3.
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.
Any questions about this release, upgrades or RabbitMQ in general are welcome on the RabbitMQ mailing list and RabbitMQ community Slack.
This release introduces Erlang 24 support and drops support for Erlang 22. Erlang 24 offers non-trivial real world throughput improvements for many RabbitMQ installations and workloads. It is expected to ship in May 2021.
In the meantime, see Provisioning Latest Erlang Releases to
learn how to provision a recent version of Erlang 23.3.
GitHub issue: #2900
This plugin was unintentionally excluded from the distribution in 3.8.15 and has now been
added back.
GitHub issue: #3023
Messaging polling HTTP API endpoint leaked temporary connections it used in case of a polling timeout. Note that this endpoint is not recommended to be used outside of QA environments. Use a long-lived consumer via one of the supported messaging protocols.
