-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2025-f6c32b0adb 2025-03-15 00:23:42.170828+00:00 -------------------------------------------------------------------------------- Name : rabbitmq-server Product : Fedora 42 Version : 4.0.7 Release : 1.fc42 URL : https://www.rabbitmq.com/ Summary : The RabbitMQ server Description : RabbitMQ is an implementation of AMQP, the emerging standard for high performance enterprise messaging. The RabbitMQ server is a robust and scalable implementation of an AMQP broker. -------------------------------------------------------------------------------- Update Information: RabbitMQ 4.0.7 Release notes can be found on GitHub at rabbitmq-server/release-notes. Core Broker Bug Fixes Classic queue message store did not remove segment files with large messages (over 4 MB) in some cases. A node with Khepri enabled would fail to start if its metadata store contained an exclusive queue with at least one binding. Enhancements Reduced memory usage and GC pressure for workloads where large (4 MB or greater) messages were published to classic queues. CLI Tools Deprecations rabbitmq-streams set_stream_retention_policy is now a no-op. It was a leftover from the early days of streams. The modern and optimal way of configuring stream retention is via a policy. Prometheus Plugin Enhancements New labels make it possible to differentiate between the metrics with the same name scraped from the aggregated metric endpoint and the per-object metric endpoint. Management Plugin Bug Fixes Who help tooltips were not updated for 4.0.x. Enhancements Consumer count is a new column that can be enabled for the channels table on the tab of the same name. Caching Authentication and Authorization Backend Plugin Enhancements rabbitmqctl clear_auth_backend_cache is a new command that clears the cache maintained by the plugin. Dependency Changes ra was upgraded to 2.15.2 RabbitMQ 4.0.6 Release notes can be found on GitHub at rabbitmq-server/release-notes. Core Broker Bug Fixes When a quorum queue leader has changed, followers were not always notified of unapplied [for/by them] log commands. Default cluster formation timeout with Khepri now matches that of Mnesia (5 minutes by default). When stream consumer was cancelled, an internal event was not emitted. Stream consumer metrics were not cleared when its respective connection was closed. Quorum queues could return a list of members (replicas) with duplicates in some cases. Classic queues with priorities could run into an exception. Corrected a log message. Enhancements A new mechanism for protecting a virtual host from deletion using metadata. CLI Tools Bug Fixes rabbitmqctl import_definitions hanged when definitions were provided via the standard input instead of a file. Enhancements rabbitmqadmin v2 has matured enough to recommend it over the original version of the tool rabbitmq-diagnostics CLI documentation was improved to clarify that all certificates discovered will be checked for expiration. New health checks for metadata store initialization: rabbitmq-diagnostics check_if_metadata_store_is_initialized rabbitmq-diagnostics check_if_metadata_store_is_initialized_with_data Prometheus Plugin Bug Fixes Improved metric description. Management Plugin Bug Fixes Pagination-related sections of the HTTP API reference were clarified to explain that the maximum page size cannot exceed 500. Empty channel_details objects are now serialized as empty objects and not empty arrays. Enhancements New health checks for metadata store initialization: GET /api/health/checks/metadata-store/initialized GET /api/health/checks/metadata-store/initialized/with-data Deprecations The original HTTP API One True Health Checkâ?¢ is now a no-op. A comparable "mega health check" has long been deprecated in CLI tools and was made a no-op in 4.0.0. This endpoint was using a deprecated feature: a classic non-exclusive transient (non-durable) queue. See Health Checks for modern focused alternatives. Consul Peer Discovery Plugin Enhancements cluster_formation.registration.enabled is a new configuration setting that allows the backend to skip registration. This is useful when Consul is used for peer discovery but a different tool such as Nomad is used to keep track of the services and their registration, unregistration. Erlang AMQP 1.0 Client Bug Fixes Purging an non-existing queue now returns a 404 response.
