Added

General

• Added WebSocket-specific ping interval configuration with ping_internal in the websocket block (#7614)

Improved

JetStream

• The scan for the last sourced message sequence when setting up a subject-filtered source is now considerably faster (#7553)
• Consumer interest checks on interest-based streams are now significantly faster when there are large gaps in interest (#7656)

MQTT

• Retained messages will now work correctly even when sourced from a different account and has a subject transform (#7636)

Fixed

General

• WebSocket connections will now correctly limit the buffer size during decompression (#7625, thanks to Pavel Kokout at Aisle Research)

JetStream

• A protocol error caused by an invalid transform of acknowledgement reply subjects when originating from a gateway connection has been fixed (#7579)
• The meta layer will now only respond to peer remove requests after quorum has been reached (#7581)
• Invalid subject filters containing non-terminating full wildcard no longer produce unexpected matches (#7585)
• A data race when creating a stream in clustered mode has been fixed (#7586)
• A panic when processing snapshots with missing nodes or assignments has been fixed (#7588)
• When purging whole message blocks, the subject tracking and scheduled messages are now updated correctly (#7593)
• The filestore will no longer unexpectedly lose writes when AsyncFlush is enabled after a process pause (#7594)
• The filestore now will process message removal on disk before updating accounting, which improves error handling (#7595, #7601)
• Raft will no longer allow peer-removing the one remaining peer (#7610)
• A data race has been fixed in the stream health check (#7619)
• Tombstones are now correctly written for recovering the sequences after compacting or purging an almost-empty stream to seq 2 (#7627)
• Combining skip sequences and compactions will no longer overwrite the block at the wrong offset, correcting a corrupt record state error (#7627)
• Compactions that reclaim over half of the available space now use an atomic write to avoid losing messages if killed (#7627)
• Filestore compaction should no longer result in no idx present cache errors (#7634)
• Filestore compaction now correctly adjusts the high and low sequences for a message block, as well as cleaning up the deletion map accordingly (#7634)
• Potential stream desyncs that could happen during stream snapshotting have been fixed (#7655)

MQTT

• The maximum payload size is now correctly enforced for MQTT clients (#7555, thanks to @yixianOu)
• Fixed a panic that could occur when reloading config if the user did not have permission to access retained messages (#7596)
• Fixed account mapping for JetStream API requests when traversing non-JetStream-enabled servers (#7598)
• QoS0 messages are now mapped correctly across account imports/exports with subject mappings (#7605)
• Loading retained messages no longer fails after restarting due to last sequence checks (#7616)
• A bug which could corrupt retained messages in clustered deployments has been fixed (#7622)
• Permissions to $MQTT. subscriptions are now handled implicitly, with the exception of deny ACLs which still permit restriction (#7637)
• A bug where QoS2 messages could not be retrieved after a server restart has been fixed (#7643)
