Go Version

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

Updated

• Dependencies (#1215)
  • Postgres v1.10.2 -> v1.10.3
  • NATS Server v2.3.3 -> v2.6.2

Improved

• Clustering:
  • Redelivery for queue members is now similar to standalone/FT mode, which means that messages will be redelivered to any member of the group (as opposed to the member that originally received the messages). Thanks to @mihai-tiriplica-f3 for the suggestion (#1214)

Fixed

• Clustering:
  • A queue member's last_sent in monitoring endpoints may be displayed as 0 on follower nodes, while it is not on the leader node. Thanks to @Xswer and @PBug90 for the report (#1213)

git remote set-head origin -a

Go Version

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

Updated

• Dependencies (#1206)
  • NATS Server v2.2.6 -> v2.3.3
  • bbolt v1.3.5 -> v1.3.6

Changed

• Executable symbol table no longer stripped (#1206)

Fixed

• Clustering:
  • Possible redelivery from a node that acquired leadership and lost it quickly after. Thanks to @piotrlipiarz-ef for the report (#1201)
  • Snapshot of queue members would not capture the last_sent value of the group, which could possibly lead to redelivery of old messages when a node became leader. Thanks to @mihai-tiriplica-f3 for the report (#1203)
• SQL:
  • A subscription's last_sent could end-up higher than the store's last_seq in presence of message expiration and server restarts (standalone or Fault Tolerance modes), which would cause the server to stop sending messages until the message sequences were above the subscription's last_sent (#1204)

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

Added

• Subscriptions count in some monitoring endpoints (#1154)
• Clustering: configuration parameters allowing configuration of some of bolt DB options. This is use for RAFT storage. The new option bolt_free_list_map may help with fragmented free list and big RAFT logs (#1159)
• Clustering: configuration parameter nodes_connections to enable creation of separate NATS connections to communicate between RAFT nodes (#1160)

Improved

• Clustering: Reduce use of locking where not needed (#1158)
• Reduce contention when sending heartbeats to clients (#1157)

Updated

• Protobuf dependencies (#1146)

Fixed

• Possibly dropping clients protocol requests (#1153)
• Fail pending subscriptions requests if the client connection is closed due to lack of heartbeats (#1161)
• Support closing of subscriptions based on subscription's Inbox instead of AckInbox. New libraries should send a subscription close request if they get a timeout on subscribe (#1162)
