Includes everything in v2.10.17-RC.3.

Go Version

• 1.22.4

Dependencies

• github.com/klauspost/compress v1.17.9 (#5538)
• github.com/nats-io/nats.go v1.36.0 (#5538)

Added

Monitoring

• Experimental /raftz monitoring endpoint for retrieving internal Raft group state for diagnostic purposes (#5530)

Improved

JetStream

• Ensure ack processing is consistent and correct between leader and followers for replicated consumers (#5524)
• Use per-subject info to speed up load-last filestore operations with wildcard filters (#5546)
• Populate missing per-subject info after skipping blocks when calculating filtered pending (#5545)
• Reduced time taken to process consumer deletes when there is a large gap between the consumer ack floor and the stream last sequence (#5547)

Fixed

JetStream

• Follower stores no longer inherit the redelivered consumer delivered sequence which could break ack gap fill (#5533)
• Direct Raft proposals will no longer bypass the internal proposal queue which could cause incorrect interleaving of state (#5543)
• Audit streams that capture $JS, $JS.API, $JSC and $SYS subjects are now only allowed if NoAck is set, avoiding potential misconfiguration that could affect the JetStream API (#5548)
• Streams from failed snapshot restores are now cleaned up correctly, fixing potential false positive warnings on /healthz after a failed restore (#5549)

Monitoring

• Ensure consistency of the delivered stream sequence in /jsz filtered consumer reporting (#5528)
