Changelog

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

Improved

JetStream

Fixed

General

• The subsz monitoring endpoint now returns the correct total for subscription details, aligning behaviour with other endpoints for pagination (#7009)

JetStream

• Fixed a bug where filestore encryption could corrupt a message block if a write took place before a read after restarting the server (#7008)
• Fixed a performance regression introduced in v2.11.0 which could result in abnormally low throughput from filtered consumers and higher GC pressure (#7015)
• Healthchecks will no longer produce unexpected monitor goroutine warnings when a clustered stream is restored from a snapshot (#7019)
• A race condition that could result in removed streams incorrectly reappearing has been fixed (#7025)
