NATS - v2.7.3

Changelog

Go Version

• 1.17.7: Both release executables and Docker images are built with this Go release.

Added

• JetStream:
  • Allow replica updates during stream update (#2867)
  • Allow stream placement by tags (#2871)

Updated

• Dependencies:
  • github.com/klauspost/compress: v1.13.4 -> v1.14.4
  • github.com/minio/highwayhash : v1.0.1 -> v1.0.2

Improved

• JetStream:
  • Sparse consumers replay time. This is when a stream has multiple subjects and a consumer filters the stream to a small and spread out list of messages (#2848, #2863)
  • Small improvements to send performance when sending to a full stream (#2877)

Fixed

• Gateway:
  • Connection could fail with 'Authorization Violation' and parser error due to an initial PING possibly sent prior to the CONNECT protocol. Also, the server accepting a connection was not starting the authentication timer, which responsibility is to close the connection if the CONNECT protocol is not received within the gateway's authentication timeout. It can be configured with authorization{ timeout: 5.0 } in the gateway{} block, but if not set will default to 2 seconds. Thanks to @jimenj1970 for the report (#2881)
• JetStream:
  • Flow control stall under specific conditions of messages size (#2847)
  • A stream name is tied to its identity and cannot be changed on restore (#2857)
  • The consumer information's state in response to a consumer create request could return inaccurate information, specially regarding number of pending messages (#2858)
  • Remove "fss" files from a snapshot when a block is removed. Thanks to @nekufa for the report (#2859)
  • Prevent a panic when stream restore fails (#2864
  • Interest policy and staggered filtered consumers could fail to remove messages. Thanks to @lukasGemela for the report (#2875)
  • Remove "key" files when removing message blocks and encryption is used. Thanks to @exename for the report (#2878)
  • Reduce logging for internal message exchange (#2879)
  • Rare possible re-use of internal RAFT inbox that could cause a node to receive a message on the wrong inbox, possibly leading to a panic. Servers would likely have to be started at the exact same time for that to happen (#2879)
