RabbitMQ 3.6.2

RabbitMQ 3.6.2 is a maintenance release that includes a new statistics
collector in the management plugin
.

Management Plugin Incompatibility with Earlier 3.6.x Releases

Because this version includes significant changes to the management plugin,
it should not be deployed into clusters with mixed 3.6.x node versions
unless all nodes that have the management plugin enabled run 3.6.2.
Otherwise HTTP API requests will fail with exceptions in some scenarios and parts of
management UI may not be updated.

There are no other known incompatibilities with earlier 3.6.x releases.

OpenSSL Requirement for Standalone Mac Release

Standalone Mac OS X package now requires OpenSSL 1.0.x to be provided by the system, for example,
from Homebrew.

Optional socat Package Dependency for Distributions that Use systemd

Starting with 3.6.2, RabbitMQ Debian and RPM packages have an optional
dependency on socat. When
installing using dpkg, this dependency won't be automatically installed. To install it manually, use

sudo apt-get install socat

Server

Bug Fixes

  • Channel operations that time out no longer produce noisy crash reports in
    RabbitMQ log files

    GitHub issue: rabbitmq-common#63

  • Channel operation timeout default is bumped to 15 seconds

    GitHub issue: rabbitmq-server/issues/667

  • Windows service will pick up RabbitMQ config file regardless of whether
    it was present during service installation

    GitHub issue: rabbitmq-server#659

  • Erlang distribution failures for rabbitmqctl and cross-node links will
    provide more detail when running on Erlang 19 (scheduled for release in Q3 2016).

    GitHub issue: rabbitmq-server#401

  • rabbitmqctl list_consumers now lists all consumers on a given queue

    Previously it would only list one.

    GitHub issue: rabbitmq-server#701

  • rabbitmqctl list_queues now correctly outputs rows for unavailable queues

    Contributed by Alexey Lebedeff (Mirantis).

    GitHub issue: rabbitmq-server#696

  • rabbitmqctl set_disk_free_limit mem_relative erroneously rejected values greater than 1.0

    GitHub issue: rabbitmq-server#717

  • Messages with an invalid client-provided x-death header value caused queue process termination

    GitHub issue: rabbitmq-server#767

  • Messages with priorities higher than queue max are now assigned max configured priority
    and no longer cause an unhandled exception that results in queue process restart

    GitHub issue: rabbitmq-server#795

  • Policy-related rabbitmqctl commands could return unformatted messages

    GitHub issue: rabbitmq-server#742

  • RABBITMQ_IO_THREAD_POOL_SIZE is no longer ignored by rabbitmq-server.bat

    GitHub issue: rabbitmq-server#705

  • Deleting a vhost in parallel with updating a policy in it resulted
    in unhandled exceptions

    GitHub issues: rabbitmq-server#755,
    rabbitmq-server#759,
    rabbitmq-server#744

Enhancements

  • Connections now emit stats unconditionally when they are blocked and unblocked
    by resource alarms. This makes management UI and HTTP API-reported data to be more up-to-date

    GitHub issue: rabbitmq-server#679

  • New (node-local) health check command

    rabbitmqctl node_health_check is a new command that performs basic health check of a node

    GitHub issue: rabbitmq-server#398

  • Automatic restart policy enabled for Windows service

    GitHub issue: rabbitmq-server#645

  • Default number of async I/O VM threads is now calculated based on the
    number of available CPU cores

    GitHub issue: rabbitmq-server#151

  • rabbitmqctl list_queues now supports new flags, --offline and --online, that limit
    result to only unavailable or available queues (queue masters, to be more precise)

    Contributed by Alexey Lebedeff (Mirantis).

    GitHub issue: rabbitmq-server#688

  • RabbitMQ will no longer log a warning about disabled kernel polling on Windows

    The runtime does not support kernel polling (I/O completion ports) on Windows,
    so there is nothing the user can do about it.

    GitHub issue: rabbitmq-server#695

  • Queue index is now updated in batches when messages are requeued

    GitHub issue: rabbitmq-server#343

Upgrading

To upgrade a non-clustered RabbitMQ simply install the new version. All configuration and persistent message data are retained. When upgrading using definitions export/import from versions earlier than 3.6.1, see http://rabbitmq.com/passwords.html.

To upgrade a RabbitMQ cluster, follow the instructions in RabbitMQ documentation. All nodes that have RabbitMQ management plugin enabled
must be upgraded in lock step.
