RabbitMQ 3.7.9 已发布，这是一个维护版本，主要聚焦于修复 bug 和可用性改进。

兼容性说明

此版本与早期的 3.7.x 没有已知的不兼容性。

升级至 Erlang 21.0

升级该版本会同时将  Erlang 更新至 21.0 版本。

具体更改

Core Server

Bug Fixes

• Queue deletion loaded bindings in an inefficient way.

  GitHub issue: rabbitmq/rabbitmq-server#1690

• Heartbeat monitor now correctly sends heartbeats at half the negotiated timeout interval.
  It previously could fail to do so because it considered its own traffic to be on-the-wire
  activity from the peer.

  GitHub issue: rabbitmq/rabbitmq-common#278

• Nodes were using a [client] Syslog UDP socket even when logging to Syslog was not enabled.

  GitHub issue: rabbitmq/rabbitmq-server#1718

• ERL_EPMD_PORT was ignored when configured in rabbitmq-env.conf.

  GitHub issue: rabbitmq/rabbitmq-server#1709

• Proxy Protocol dependency is now compatible with Erlang/OTP 21.

  GitHub issue: rabbitmq/rabbitmq-common#269

Enhancements

• It is now possible to configure cipher suites using new style config format.

  GitHub issue: rabbitmq/rabbitmq-server#1712

• When a listener fails to start (bind to a server socket), error messages involve less context and are
  easier to read.

  GitHub issue: rabbitmq/rabbitmq-server#1711

• Improved error reporting for when erl or erl.exe are no in node's PATH.

  GitHub issue: rabbitmq/rabbitmq-common#275

• 10 TLS connection acceptors are now used by default.

  GitHub issue: rabbitmq/rabbitmq-server#1729

CLI Tools

Bug Fixes

• rabbitmqctl list_* commands did not include table column headers.

  GitHub issue: rabbitmq/rabbitmq-cli#264

• If RABBITMQ_NODENAME is configured, CLI tools will use its hostname part when generating its own
  Erlang node name.

  GitHub issue: rabbitmq/rabbitmq-cli#270

• On Windows CLI tool batch scripts exited with a 0 exit code when it failed to connect to the node.

  Contributed by Artem Zinenko.

  GitHub issue: rabbitmq/rabbitmq-server#1735.

Enhancements

• rabbitmq-plugins directories is a new command that outputs effective plugin directories.

  GitHub issue: rabbitmq/rabbitmq-cli#261

• rabbitmqctl stop now supports --idempotent that makes the command exit with a success when
  target node is not running.

  GitHub issue: rabbitmq/rabbitmq-cli#272

• rabbitmqctl add_vhost is now idempotent (no longer returns an error when vhost already exists)

  GitHub issue: rabbitmq/rabbitmq-cli#260

Management and Management Agent Plugins

Bug Fixes

• Logo link now works better with a non-blank API endpoint prefix.

  GitHub issue: rabbitmq/rabbitmq-management#604

• Decimal headers and argument values are now serialised to JSON correctly.

  GitHub issue: rabbitmq/rabbitmq-management-agent#71

Enhancements

• It is now possible to configure both HTTPS and HTTP listeners using new syntax that's consistent with
  Web STOMP and Web MQTT plugins:

  management.tcp.port = 15672
  
  management.ssl.port = 15671
  management.ssl.cacertfile = /path/to/cacert.pem
  management.ssl.certfile = /path/to/cert.pem
  management.ssl.keyfile = /path/to/key.pem

  GitHub issue: rabbitmq/rabbitmq-management#563

• GET /api/nodes/{node} endpoint aggregated data for other cluster nodes only to discard it later.

  GitHub issue: rabbitmq/rabbitmq-management#615

• When Handle.exe is used and returns no file handle information in its output, a warning will be logged.

  GitHub issue: rabbitmq/rabbitmq-management-agent#67

LDAP Plugin

Enhancements

• String matching queries now support multi-value results.

  GitHub issue: rabbitmq/rabbitmq-auth-backend-ldap#100

• ad_domain and ad_user are new variables available in LDAP plugin queries. They are extracted from the username
  when it's in Domain\User format, which is typically specific to ActiveDirectory.

  GitHub issue: rabbitmq/rabbitmq-auth-backend-ldap#98

• Search queries that return referrals will result in an error instead of an exception.

  GitHub issue: rabbitmq/rabbitmq-auth-backend-ldap#97

Web STOMP Plugin

Enhancements

• Advanced WebSocket options now can be configured. Compression is enabled by default.
  Compression won't be used with clients that do not support it.

  GitHub issues: rabbitmq/rabbitmq-web-stomp#89, rabbitmq/rabbitmq-web-stomp#90

Web MQTT Plugin

Bug Fixes

• WebSocket PING frames are now ignored instead of being propagated to MQTT frame handler.

GitHub issue: rabbitmq/rabbitmq-web-mqtt#32

Enhancements

• Advanced WebSocket options now can be configured. Compression is enabled by default.
  Compression won't be used with clients that do not support it.

  GitHub issues: rabbitmq/rabbitmq-web-mqtt#34

AWS Peer Discovery Plugin

Bug Fixes

• EC2 API endpoint requests used an unreasonably low timeout (100 ms). The new value
  is 10 seconds.

  GitHub issue: rabbitmq/rabbitmq-peer-discovery-aws#24

Consul Peer Discovery Plugin

Bug Fixes

• It wasn't possible to specify Consul service tags via new style config format.

GitHub issue: rabbitmq/rabbitmq-peer-discovery-consul#18

• It wasn't possible to configure lock key prefix via new style config format.

GitHub issues: rabbitmq/rabbitmq-peer-discovery-consul#16

Enhancements

• Lock acquisition timeout now can be configured using cluster_formation.consul.lock_timeout as well as cluster_formation.consul.lock_wait_time (an alias),
  to be consistent with the Etcd implementation.

  GitHub issue: rabbitmq/rabbitmq-peer-discovery-consul#20

Etcd Peer Discovery Plugin

Enhancements

• Lock acquisition timeout now can be configured using cluster_formation.etcd.lock_timeout as well as cluster_formation.etcd.lock_wait_time (an alias),
  to be consistent with the Consul implementation.

  GitHub issue: rabbitmq/rabbitmq-peer-discovery-etcd#16

Event Exchange Plugin

Enhancements

• Throughput optimizations reduce probability of high memory consumption by rabbit_event processes due to
  event backlog accumulation.

  GitHub issue: rabbitmq/rabbitmq-server#1722

RPM Package

Bug Fixes

• Post-installation script renamed rabbitmq.conf to rabbitmq-env.conf. A long time ago rabbitmq.confwas used to configure
  environment variables (like rabbitmq-env.conf today) and old post-installation steps were not removed when rabbitmq.conf
  was re-adopted for new style config files.

  GitHub issue: rabbitmq/rabbitmq-server-release#87
