Go Version

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

Added

• Configuration:
  • Ability to configure account limits (max_connections, max_subscriptions, max_payload, max_leafnodes) in server configuration file (#2755)
• JetStream:
  • Overflow placement for streams. A stream can now be placed in the closest cluster from the origin request if it can be placed there (#2771, #2779)
  • Support for ephemeral Pull consumers (client libraries will need to be updated to allow those) (#2776)
  • New consumer configuration options (#2776):
    • For Pull Consumers:
      • MaxRequestBatch to limit the batch size any client can request
      • MaxRequestExpires to limit the expiration any client can request
    • For ephemeral consumers :
      • InactiveThreshold duration that instructs the server to cleanup ephemeral consumers that are inactive for that long
  • Ability to configure max_file_store and max_memory_store in the jetstream{} block as strings with the following suffixes K, M, G and T, for instance: max_file_store: "256M". Thanks to @​hooksie1 for the contribution (#2777)
  • Support for the JWT field MaxBytesRequired, which defines a per-account maximum bytes for assets (#2779)
• MQTT:
  • Support for websocket protocol. MQTT clients must connect to the opened websocket port and add /mqtt to the URL path. Thanks to @​Etran-H for the suggestion (#2735)
• TLS:
  • Ability to rate-limit the clients connections by adding the connection_rate_limit: <number of connections per seconds> in the tls{} top-level block. Thanks to @​julius-welink for the contribution (#2573)

Improved

• JetStream:
  • MemStore is improved in the presence of a lot of interior delete messages, which could happen for instance with the use of KV store (#2752)
  • Pull consumers behavior: more resilient, better at waiting request management, and the ability to determine and watch interest cross account (#2776)
  • In clustering mode, with streams with replication factor greater than 1, a server will now use much less memory. For instance: 1,000 streams, with 10 consumers each would use about 15GB of memory, with this change memory usage would go down to about 1.5GB (#2775)
• Monitoring:
  • Make the HTTP(s) monitoring endpoints available before starting JetStream to be able to monitor whether it is available during startup and recovery of streams. This could help with health probes (#2782)
• Websocket:
  • Added client IP from X-Forwarded-For header. Thanks to @​byazrail for the suggestion (#2734, #2769)

Changed

• JetStream:
  • JetStream API traffic will now be denied across leaf nodes, unless the system account is shared and the availability domain is identical (#2693)

Updated

• Some dependencies (#2727)

Fixed

• JetStream:
