## Changelog

Refer to the [2.15 Upgrade Guide](https://docs.nats.io/release-notes/upgrade-to-2.15) for backwards compatibility notes with 2.14.x. This release also contains all changes up to and including [v2.14.7](https://github.com/nats-io/nats-server/releases/tag/v2.14.7).

### Go Version

• 1.27.1 (#8551)

### Added

JetStream

• Desired state metalayer (#8432, #8437, #8439, #8443, #8452, #8460, #8476, #8576, #8598, #8602, #8603)
• A new desired state reconciliation engine for streams and consumers considerably improves the safety and reliability of asset moves and scales
• Updating the placement or replication factor midway through an existing scale/move operation, cancelling an in-flight scale/move, or peer-removing is now much safer
• ADR：https://github.com/nats-io/nats-architecture-and-design/blob/main/adr/ADR-62.md
• Cancel stream move endpoint (#8476)
• An in-flight scale/move operation on a stream can be cancelled and the asset returned to its original placement using the new `$JS.API.STREAM.CANCEL_MOVE` endpoint
• ADR：https://github.com/nats-io/nats-architecture-and-design/blob/main/adr/ADR-62.md
• Evacuate endpoints (#8443)
• The new `$JS.API.SERVER.EVACUATE` endpoint can safely evacuate streams, and any consumers on those streams, from a node
• The new `$JS.API.STREAM.PEER.EVACUATE.*` endpoint can safely evacuate a peer, and any consumers on that peer, from a stream
• These operations combined allow for maintenance operations with full transfer of data and state without having to peer-remove first
• ADR：https://github.com/nats-io/nats-architecture-and-design/blob/main/adr/ADR-62.md
• Metalayer rescue for disaster recovery (#8408)
• The new `$JS.API.META.RESCUE` endpoint can temporarily lower the quorum-needed for the metalayer, in order to facilitate the recovery of a system where nodes have been permanently lost and the metalayer cannot reach quorum
• ADR：https://github.com/nats-io/nats-architecture-and-design/blob/main/adr/ADR-61.md
• Stream backup and restore v2 (#7882, #8584, #8591, #8604)
• A new backup format for stream snapshots which reads out per-message rather than per-block
• The new backup format also now correctly includes non-replicated consumers on follower nodes
• ADR：https://github.com/nats-io/nats-architecture-and-design/blob/main/adr/ADR-63.md
• Detect source stream recreation (#8384)
• The server now detects a source stream being recreated, restarting the sourcing back from the beginning, ensuring new messages are sourced
• Stream source indexing (#8282, #8516, #8283)
• Restarts and leader changes previously required expensive backward scans through the stream to find the last sourced indices. These are now persisted in an index for instant lookup.
• Domain-prefixed JS API in system account (#8429)
• When a system account is bridged between the hub and a leaf node, the domain-prefixed JS API can now be used to operate on the leaf node while directly connected to the hub

### Changed

JetStream

• Streams now have a default limit of 1000 consumers, unless `max_consumers` is specified in the stream config or account limits (#8337, #8566)
• Applications planning to use a large number of consumers on a stream should configure `max_consumers` in the stream config or account limits to an appropriately high number
• The server-wide default of 1000 can be overridden by setting `default_max_consumers` in the JetStream limits, or can be disabled by setting to `-1`
• This limit does not affect existing consumers and will not result in consumer deletions, only the creation of new consumers is prevented
• Sync changes for replicated streams (#8447)
• When the `sync_interval` is set to `always`, replicated streams now sync their WAL entries but no longer sync upper stream layer writes
• The synced log allows the stream to recover safely, but removing unnecessary syncs from the upper stream layer dramatically improves performance
• Non-replicated R1 streams are not affected by this change and will continue to sync at the stream layer as normal
• The `js_raft_delete_range` feature is now enabled by default (#8520)

Leafnodes

• The `no_advertise` option no longer includes the hub's own listener address (#8451, contributed by @freakes)

### Improved

JetStream

• Shorter wait for durable source/mirror consumer resets (#8323)
• When using durable consumers for sourcing or mirroring, the heartbeats now short-circuit the recreation backoff
• An atomic batch for a single-replica stream run with `sync：always` now syncs messages as a group (#8539, contributed by @RainyPixel)
• JetStream source/mirror reply subjects can now opt-in to be domain/account aware (#8586, contributed by @ayushk-1801)

MQTT

• QOS 1 published into JetStream are pipelined for increased throughput (#8415, contributed by @levb)

### Fixed

Leafnodes

• Leafnode isolation using `request_isolation`, or with hub-enforced `isolate`, now works correctly across cluster nodes (#8504)
