RabbitMQ 3.11.1 发布

RabbitMQ 3.11.1 is a maintenance release in the 3.11.x release series.

Please refer to the upgrade section from v3.11.0 release notes
if upgrading from a version prior to 3.11.0.

This release requires Erlang 25.
RabbitMQ and Erlang/OTP Compatibility Matrix has more details on
Erlang version requirements for RabbitMQ.

Minimum Supported Erlang Version

Starting with this release, RabbitMQ requires Erlang 25. Nodes will fail to start on older Erlang releases.

Erlang 25 as our new baseline means much improved performance on ARM64 architectures, profiling with flame graphs
across all architectures, and the most recent TLS 1.3 implementation available to all RabbitMQ 3.11 users.

Changes Worth Mentioning

Release notes can be found on GitHub at rabbitmq-server/release-notes.

Core Server

Bug Fixes

• A rolling upgrade on Kubernetes could hang.

  GitHub issue: #6034

• In mixed 3.11/3.10 clusters, channels that performed operations on classic queues could
  run into an exception.

  GitHub issue: #5931

• A quorum queue consumer was cancelled and immediately re-registered while some
  deliveries were in flight could result in a channel exception.

  GitHub issue: #5927

• More strings from external sources are converted to Unicode-aware representation
  internally, in log messages, CLI tools output and UI, and so on.

  GitHub issues: #5551

• During plugin activation on a running node, plugins with dependencies were added to runtime code path
  in an order that could break if a plugin had hard transitive dependencies (that must be loaded first).

  GitHub issue: #6019

Enhancements

• Support for paths with non-ASCII (Unicode) characters in paths.
• rabbitmq-diagnostics observer now includes a new tab that provides access to internal classic queue
  metrics.

  GitHub issue: #6074

  GitHub issue: #5831

Stream Plugin

Bug Fixes

• Replicas of a stream that had a Single Active Consumer on it could run into an exception.

  GitHub issue: #5889

• Stream protocol implementation used incorrect keys in RouteResponse and PartitionResponse frames.

  GitHub issue: #5956

Enhancements

• When a superstream (partitioned stream) is added using CLI tools, its primary replica will now
  be placed according to the balanced leader placement strategy. Previously it was using “node local”
  which resulted in much less even superstream leader replica distribution across cluster nodes.

• rabbitmqctl list_amqp10_connections were not listing connections correctly.

  GitHub issue: #4238
