Server

Bug Fixes

Purging a lazy queue could result in an exception
GitHub issue: rabbitmq-server#514
Ensure epmd is running before starting RabbitMQ node on Windows
GitHub issue:rabbitmq-server#625
Channel error could make broker unreachable
Those errors were misleadingly logged aschannel_termination_timeout, which
the issue really was with unhandled messages from concurrently closed TCP socket process.

GitHub issue: rabbitmq-server#530
(Automatic) deletion of an auto-delete queue could lead
to blocked channels

GitHub issue: rabbitmq-server#581
During (from scratch) queue sync, queue master node didn’t respect mirror alarm state.
With large data sets this could drive mirror node out of memory.

GitHub issue: rabbitmq-server#616
Changing password for users with non-standard (think broker configuration) password
hashing function, for example, those migrated from 3.5.x releases, didn’t update
effective hashing function.

GitHub issue: rabbitmq-server#623
Heavy and/or prolonged rabbitmqctl use could exhaust Erlang VM atom table
GitHub issue: rabbitmq-server#549
“Min masters” queue master location strategy could result
in an error.

GitHub issue: rabbitmq-server#521
Fixed a race condition in pause_minority handling mode.
GitHub issue: rabbitmq-server#307
Significantly reduce possibility of a race condition when
an exchange is deleted and immediately re-declared, e.g. by a federation
link.

This could result in a link operation being blocked, preventing
nodes from stopping.

GitHub issue: rabbitmq-federation#7
amq.rabbitmq.log messages now have information about originating
node in message headers

GitHub issue: rabbitmq-server#595
scripts/rabbitmq-env now works with GNU sed 4.2.2
GitHub issue: rabbitmq-server#592
Exceptions in VM memory use calculator no longer affect broker startup
GitHub issue:rabbitmq-server#328
Direct Reply-to capability is now advertised to clients
GitHub issue: rabbitmq-server#520

Enhancements

Paths with non-ASCII characters on Windows are now handled
RabbitMQ now can be installed into a location with non-ASCII characters,
e.g. when username contains them.

GitHub issues: rabbitmq-server#493
Configurable number of TCP connection acceptors
Plus a x10 increase of the default. This helps with workloads where connection
churn is very high (e.g. all clients are PHP Web apps that cannot maintain
long-lived connections).

GitHub issues: rabbitmq-server#528
rabbitmqctl cluster_status now includes cluster-wide resource alarm status
GitHub issue:rabbitmq-server#392
Windows installer no longer jumps over installation log
GitHub issue: rabbitmq-server#634
Improved rabbitmqctl reset error messages
GitHub issue: rabbitmq-server#167
More unsigned field data types are supported.
GitHub issue: rabbitmq-server#20

Java client

Enhancements

Endpoints (hostnames) are now also accepted as a java.util.List
GitHub issue: rabbitmq-java-client#125
Autorecovering connections now shuffle hosts in a more
reliable way

GitHub issue: rabbitmq-java-client#124

Bug Fixes

Binding recovery could fail
GitHub issue: rabbitmq-java-client#129
Channel.queueDelete could throw a NullPointerException
GitHub issue: rabbitmq-java-client#120

.NET client

Bug Fixes

Autorecovering connections now use full list of provided hostnames
during recovery

GitHub issues: rabbitmq-dotnet-client#153

Federation Plugin

Bug Fixes

Significantly reduce possibility of a race condition when
an exchange is deleted and immediately re-declared, e.g. by a federation
link

This rendered federation links dysfunctional.

GitHub issue: rabbitmq-federation#7

Management plugin

Vulnerability Fixes

CVE-2015-8786: user-provided query parameters lengths_age and lengths_incr had no validation
and could be used to exhaust server resources.

The attacker needs to have access to HTTP API (authenticate successfully and have sufficient
tags to pass authorisation) in order to carry out the attack.

There is no workaround for earlier releases.

Kudos to Vladimir Ivanov (Positive Technologies) for the responsible disclosure.

GitHub issue: rabbitmq-management#97

Enhancements

Password hashing function is now included in exported definitions
Those upgrading from versions earlier than 3.6.0 via definitions export
won’t have to temporarily set hashing function to MD5 to ensure export succeeds.

GitHub issue: rabbitmq-management#117

Bug Fixes

Internet Explorer (9+) compatibility restored
GitHub issue: rabbitmq-management#98
Internet Explorer 11 compatibility fixes
GitHub issues: rabbitmq-management#112,
rabbitmq-management#114
When policy fails to be created with invalid paramaters a sensible
error message will be displayed.

GitHub issue: rabbitmq-management#110

Federation Management plugin

Enhancements

Federation link form now includes more settings (that are exchange- and queue-federation specific)
GitHub issue: rabbitmq-federation-management#5

Erlang client

Bug Fixes

password and depth query parameters are now propagated to TLS options
GitHub issue:rabbitmq-erlang-client#36

STOMP plugin

Bug Fixes

durable and persistent headers weren’t always used interchangeably,
leading to non-durable subscriptions

GitHub issue: rabbitmq-stomp#58
Client heartbeat timeouts resulted in confusing error messages
in broker log.

GitHub issues: rabbitmq-stomp#63

Web STOMP plugin

Bug Fixes

Cowboy options are now supported for TLS listeners.
GitHub issue: rabbitmq-web-stomp#36

Web STOMP Examples plugin

Bug Fixes

Multi-byte UTF-8 characters are now handled
by the bundled version of stomp.js.

GitHub issue: rabbitmq-web-stomp-examples#2

Event Exchange plugin

Bug Fixes

Event timestamps are now in seconds, not milliseconds
Per AMQP 0-9-1 spec. This is not a particularly great choice for events,
so we will add an optional header with millisecond precision in a future release.
