Go Version

• 1.24.2

Dependencies

• github.com/nats-io/nats.go v1.41.2 (#6805)
• github.com/nats-io/nkeys v0.4.11 (#6805)
• github.com/nats-io/jwt/v2 v2.7.4 (#6813)

Added

General

• Support for a default sentinel JWT, which is used in operator mode when none is specified, has been added making it possible to have default users (#6577)
• New trace_headers option to ensure that trace logging only emits headers and not message payloads (#6638)

JetStream

• Subject delete markers are now placed for messages that have aged out due to their TTL and not just because of the MaxAge policy (#6741)

Improved

General

• The publish permissions cache should now remain under the max allowed size more aggressively with improved pruning (#6674)
• It is now possible with service imports to import the same subject from multiple different accounts (#6704)
• Updating an account claim with a reduced max connection count no longer causes internal clients to be closed, fixing cases where JetStream assets could become unavailable (#6785)
• GOMAXPROCS and GOMEMLIMIT are now reported in both statsz and varz (#6791)
• Improved tls_timeout configuration parsing consistency between authorization and timeout (#6731)
• Allow servers with different pool sizes when using multiple routes, simplifying configuration changes and rolling updates (#6676)
• Auth tokens are now redacted in trace-level logs for enhanced security (#6808)
• Trapped signals are now logged at notice level instead of debug (#6800)

JetStream

• Improved purge performance, particularly for KV PurgeDeletes calls, with optimised code paths for finding last sequences and reducing allocations (#6801, #6825)
• Improved replicated asset creation performance by campaigning for group leadership more quickly (#6697)
• Improved the debug log message when resetting a group WAL after failing to truncate (#6705)
• Improved checking for streams that overlap with JS API or system subjects, so that badly-configured streams should not be able to break the API (#6786)
• Allow setting per-message TTLs to values lower than the configured SubjectDeleteMarkerTTL when the stream has a max messages per subject limit of 1 (#6818)
• Servers that have been peer-remove'd can now be re-admitted automatically after 5 minutes without a server restart (#6815)

Fixed

General

• Fix a possible panic when a subject transform has missing tokens (#6612)
• Fix a possible panic when adding dedicated routes during a configuration reload (#6668)
• Data race when shutting down eventing has been resolved (#6620)
• A deadlock when updating account claims with service imports/exports has now been fixed (#6726)
• The jsz monitoring endpoint now correctly paginates with offset (#6794, #6816)
• Parsing the cluster_traffic option at startup no longer results in a panic if the account has not loaded yet (#6733)

JetStream

• Fix clustered consumer consistency problems by waiting for delivered state to reach quorum before delivering new messages, resolving issues where acknowledged messages could be redelivered after a consumer leader change
  • NOTE: This may negatively impact the throughput of replicated consumers. R1 consumers, consumers with AckNone ack policy and ordered consumers are not affected and may be more suitable for high-speed processing
• JetStream is no longer incorrectly disabled when specifying --js and --store_dir on the command line and then issuing a configuration reload (#6609)
• Correctly remove messages from an interest-based stream when using AckAll consumers (#6587)
• Preserve the first sequence when rebuilding state due to invalid checksums with no remaining messages (#6647)
• When recovering from disk, ignore temporary files that can be created during stream compression so that the same blocks do not get loaded more than once (#6684)
• Do not incorrectly reset group WALs when a new leader sends matching term information after a snapshot (#6691)
• Corrected a regression in the memory store when purging, aligning it with the filestore behaviour (#6714)
• When issuing a peer remove on a stream, the new peer set is now proposed through the NRG layer, potentially avoiding a drift in peers (#6720)
• When issuing a peer remove on a consumer, the new peer set is now proposed through the NRG layer, potentially avoiding a drift in peers (#6727)
• A race condition that could result in observer nodes becoming incorrectly elected as a group leader has been fixed when using leafnodes with shared system accounts (#6730)
• Ensure that duplicate Raft groups are not created for the same asset during a restart (#6732)
• Allow the use of the extended consumer create API when combining service imports/exports and limited API permissions (#6759)
• Streams with the FirstSeq configured are no longer incorrectly purged after a restart if the stream first sequence still matches the configured first sequence (#6753)
• Correctly write tombstones when purging and compacting, fixing a bug that could result in some deleted messages returning if the stream index had to be rebuilt (#6685)
• The memory store no longer leaks memory tracking deleted sequences after a full stream purge (#6769)
• Correctly handle acks for subjects that include a @ character (#6777)
• Avoid losing stream sequence numbers of the server is interrupted by generating a new last message block before removing the final remaining block, particularly noticeable with WQ or interest retention policies (#6778)
• Use the correct floor when using AckAll in R1 consumers (#6790)
• Preserve consumer state when a stream needs to be reset due to a failed catchup (#6796)
• Correctly enforce the 32MB maximum publish size limit into JetStream, avoiding filestore corruption from overflowing the maximum record length (#6798)
• Preserve the redelivered state if the consumer leader is placed on a server that is a lagging stream follower to keep accounting correct (#6698)
• Idempotent stream or consumer creations on a server upgrade from 2.10.x will no longer fail due to metadata changes (#6716)

• Message TTLs are now recovered properly from multiple messages if the timed hash wheel state is lost or corrupted on disk (#6758)
• Consumer priority groups will no longer get stuck in a tight-loop if there are multiple requests from different clients but some are not receiving due to the priority policy (#6749)
• Subject delete markers are now replicated more reliably and are now retriable, improving consistency in clustered mode (#6776)
• Tombstones are now correctly written for messages that have aged out due to their TTL, such that the deletion is preserved if the stream state is rebuilt (#6781)
• Corrected an off-by-one error that could cause the TTL state to be rebuilt unnecessarily on a server restart (#6679)
• Fixed a race condition in the timed hash wheel that could result in an underflow of the hash count (#6787)
• Push consumers are no longer incorrectly marked as inactive after a delivery failure if there is continued interest (#6807)
• Internal clients for JetStream are no longer closed unexpectedly after updating an expired account claim (#6817)
• Fixed a panic that could potentially occur when starting clustered consumers when the metalayer is shutting down (#6823)
