nats-io/nats-server v2.11.10-RC.1 on GitHub

Changelog

Refer to the 2.11 Upgrade Guide for backwards compatibility notes with 2.10.x.

General

Statistics for gateways, routes and leaf connections are now correctly omitted from accstatsz responses if empty (#7300)

JetStream

Stream assignment check has been simplified (#7290)
Additional guards prevent panics when loading corrupted messages from the filestore (#7299)
The store lock is no longer held while searching for TTL expiry tasks, improving performance (#7344)
Removing a message from the TTL state is now faster (#7344)
The filestore no longer performs heap allocations for hash checks (#7345)
Meta snapshot performance for a very large number of assets has been improved after a regression in v2.11.9 (#7350)
Sequence-from-timestamp lookups, such as those using opt_start_time on consumers or start_time on message get requests, now use a binary search for improved lookup performance (#7357)

General

Fixed the exit code when receiving a SIGTERM signal immediately after startup (#7367)

JetStream

Fixed a use-after-free bug and a buffer reclamation issue in the filestore flusher (#7295)
Direct get requests now correctly skip over deleted messages if the starting sequence is itself deleted (#7291)
The Raft layer now strictly enforces that non-leaders cannot send append entries (#7297)
The filestore now correctly handles recovering filestore blocks with out-of-order sequences from disk corruption (#7303, #7304)
The filestore now produces more useful error messages when disk corruption is detected (#7305)
Removed messages with a per-message TTL are now removed from the TTL state immediately (#7344)
Fixed a bug where TTL state was recovered on startup with subject delete markers enabled, that message expiry would not start as expected (#7344)
Expiring messages from the filestore no longer leaks timers and expires at the correct time (#7344)
Deleting a non-existent sequence on a stream no longer results in a cluster reset and leadership election (#7348)
Subject tree intersection now correctly handles overlapping literals and partial wildcards, i.e. stream.A and stream.*.A, fixing some consumer or message get filters (#7349)
A data race when checking all JetStream limits has been fixed (#7356)
Raft will no longer trigger a reset of the clustered state due to a stream snapshot timeout (#7293)
