RabbitMQ 3.7.11

RabbitMQ 3.7.11 is a maintenance release. It focuses on bug fixes and
minor usability improvements. This is the first release to require Erlang/OTP 20.3+.

Erlang/OTP Compatibility Notes

Per the new Erlang version support policy in effect starting with January 2019,
this release drops support for 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 20.3.x and 21.x.

Compatibility Notes

  • This release requires Erlang/OTP 20.3 or later.
  • Default CLI command exit code has changed from 70 (EX_UNAVAILABLE) to 69 (EX_SOFTWARE).
    This does not affect all commands and all error conditions, e.g. argument validation still uses code 64 (EX_USAGE)

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.

Documentation Guides and Change Log

See 3.7.0 release notes upgrade and
compatibility notes if upgrading from an earlier release.

See the Upgrading guide for general documentation on upgrades and
RabbitMQ change log for release notes of other releases.

Changes

Core Server

Erlang Version Requirement

Bug Fixes

  • Number of socket file descriptors used is now correctly incremented.

    GitHub issue: rabbitmq/rabbitmq-management#652

  • Configuration schema file was not copied during upgrades.

    GitHub issues: rabbitmq/rabbitmq-server#1843

  • First heartbeat frame on a successfully negotiated connection is now sent after a half of the negotiated heartbeat
    timeout. Previously it was sent after a complete timeout. Since most connections have other activity after
    connection handshake is complete, this didn't have any visible effects on most systems.

    GitHub issue: rabbitmq/rabbitmq-common#293

  • If Syslog was configured to use TCP, the node could fail to start.

    GitHub issue: rabbitmq/rabbitmq-server#1850
