Changes

Core Server

Bug Fixes

• Logging to amq.rabbitmq.log exchange is available again as a logging mechanism. Note that
  the user must opt-in by setting log.exchange = true in the config file.

  GitHub issue: rabbitmq-server#1456

• During node boot, the logger will temporarily accept a much higher maximum rate so that no messages are dropped.

  GitHub issue: rabbitmq-server#1471

• Plugin activation could hang if a plugin's channel interceptor failed to activate with an exception.

  GitHub issue: rabbitmq-server#1477

• During node boot, virtual host that are not yet initialised could be queried for status, which
  resulted in log noise.

  GitHub issue: rabbitmq-server#1472

Enhancements

• Internal authN backend will now prohibit logins with blank passwords. Such attempts
  are usually made by mistake because a passwordless user that was meant to authenticate
  using x509 (TLS) certificates was not configured to use the correct authentication
  mechanism.

  Note that the same behavior can already be achieved using a credential validator, so this is
  just an extra safety measure.

  GitHub issue: rabbitmq-server#1465

Management Plugin

Bug Fixes

• Definition import now stores global parameters in a way that the MQTT plugin expects.

  GitHub issue: rabbitmq-management#528

• User update form now successfully updates tags for passwordless users (or if the password is cleared at the same time).

  GitHub issue: rabbitmq-management#533

Enhancements

• Requeue is now the default option in the Get Messages section.

  GitHub issue: rabbitmq-management#542

• For passwordless users, the "no password" option on the user editing form is now preselected.

  GitHub issue: rabbitmq-management#537

LDAP AuthN/AuthZ Backend Plugin

Bug Fixes

• More config keys are now supported via new style config format.

  GitHub issue: rabbitmq-auth-backend-ldap#78

Peer Discovery Consul Plugin

• When a node registers with Consul it will now set its initial health check status to passing.
  Previously the node would be in the critical state until it first reported its health for the
  first time (in 15 seconds with default settings), which could prevent its peers from discovering it.

  Kudos to @andersenleo for investigating this issue and recommending a solution.

  GitHub issue: rabbitmq-peer-discovery-consul#8

CLI Tools

Bug Fixes

• CLI tools honor RABBITMQ_CTL_ERL_ARGS again.

  GitHub issue: rabbitmq-server#1461
