RabbitMQ 3.7.9
RabbitMQ 3.7.9
RabbitMQ 3.7.9
is a maintenance release. It focuses on bug fixes and minor usability improvements.
Compatibility Notes
CLI tools in this release will often produce an extra line of output, as they did in 3.6.x
releases,
when -q
is not provided. Tools that parse CLI command output should use -q --no-table-headers
to suppress all additional output meant for interactive use or
avoid parsing output entirely (e.g. use the HTTP API).
Upgrading to Erlang 21.0
When upgrading to this release and upgrading Erlang to 21.0 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.
