Go Version

• 1.26.7

Improved

General

• Removal from service import response maps is now constant-time (#8463)
• The client code no longer resets the deadline more times than necessary when flushing client buffers (#8513)
• The client write buffers are now freed correctly when the working buffer exceeds a rational size (#8515)

JetStream

• Stream reads are now isolated with a separate lock, which improves the performance of direct gets (#8486)
• Improved the performance of looking up matching sequence numbers for multi-subject gets (#8486)
• Reduced the number of heap escapes in subject tree matching (#8526)

Fixed

General

• WebSocket client buffers are recycled more aggressively when reallocating into larger buffers (#8518)
• Fixed missing routes after a reconnect when gossiped URLs were rejected (#8527)

JetStream

• The filestore block sync no longer incorrectly skips blocks that were compacted during the same pass (#8456)
• The filestore block sync now performs a single directory sync upon completion rather than once per compacted block (#8461)
• The filestore I/O semaphore now covers block sync operations (#8462)
• Stream config updates with replicas greater than 1 are now rejected on non-clustered systems (#8464)
• Fixed some issues that could prevent stream snapshots from taking place on a clean shutdown (#8465)
• The filestore inline compaction no longer ignores sync_interval: always (#8475)
• The stream created time is now preserved after recovery on a standalone server (#8471, contributed by @​Green7)
• Fixed a data race that could apply when accessing the batch ID (#8369)
• Fixed a data race when reading the consumer direct or sourcing status (#8478, contributed by @​nberlee)
• Prevent the consumer direct or sourcing status from being changed with a consumer update (#8478, contributed by @​nberlee)
• Fixed an issue where the server could fail to distinguish consumer tiers when enforcing limits (#8484)
• Fixed a flow control problem where replicated consumers could get stuck after a leader change (#8488)
• Fixed various consumer create issues that could destroy the state of an existing consumer with the same name (#8491)
• Internal message delete proposals are no longer counted in the JS API statistics (#8502)
• Dynamic filestore reservations no longer incorrectly shrink based on used storage after restarts (#8503)
• Fixed a signalling issue that could stall Raft catchups (#8501)
• The pending append entry cache in-memory is now bounded by size as well as entry count (#8501)
• Fixed an issue where a stale snapshot from a previous Raft group could be replayed if the group name was unchanged (#8501)
