Removed

Updated

[24.2.0] - 2024-02-25

Changed

  • Set the default value of CertificateReservedNodeCommonName to empty string EventStore#4001
  • Upgrade to .NET 8. EventStore#4046
  • Don't require ReadIndex in the enumerators when subscribing from $all EventStore#4057
  • Simplified HTTP pipeline EventStore#4088
  • Do not autosize thread count and streaminfocache size in containerized environments EventStore#4103
  • Explicitly set the shutdown timeout to 5s, which was default in previous dotnet versions. Behaviour unchanged since previous release. EventStore#4110
  • Re-authorize stream access in live subscriptions when stream metadata changes. EventStore#4104
  • Re-authorize stream access in live subscriptions when default ACLs change. EventStore#4116
  • Re-authorize subscriptions to $all when its stream metadata ($$$all) changes. EventStore#4118
  • Upgrade Jint to version 3.0.0. EventStore#4121
  • Updated plugin API. EventStore#4126
  • Decouple the enumerators from gRPC so they can work directly with connectors. EventStore#3998

Added

  • gRPC stream subscriptions with smooth transitions between live and catchup. Subscriptions no longer drop with "consumer too slow" reason. EventStore#4093
  • gRPC $all subscriptions with smooth transitions between live and catchup. Subscriptions no longer drop with "consumer too slow" reason. EventStore#4117
  • General support for plugin configuration. EventStore#4130
  • Improved support for plugins to perform authorization checks. EventStore#4145
  • $mem-gossip memory stream. EventStore#4123
  • Support for a wider range of authentication plugins. (facilitates user X.509 certificates plugin) EventStore#4148
  • Support for new packaging pipeline. EventStore#4157

Fixed

  • Addressed CVE-2024-26133: Potential password leak in the EventStoreDB Projections Subsystem.

  • Report same version info when using different kind of release tags (annotated or lightweight). EventStore#4081
  • Calls to /stats/replication on a single node cluster would hang forever. EventStore#4102
  • gRPC stream subscription now receives a stream deleted exception when subscribing to a tombstoned stream from End EventStore#4108
  • gRPC stream subscription now receives CaughtUp message when subscribing to a non-existing or soft-deleted stream. Previously in such cases, the stream subscription enumerator was looping in catch-up mode until a new event is received (and thus it never sent CaughtUp to the subscription) EventStore#4108
  • Initialize replication service heartbeat interval with ReplicationHeartbeatInterval instead of NodeHeartbeatInterval . EventStore#4125
  • $all subscription enumerator returns InvalidPosition when subscribing at an invalid position. EventStore#4128
  • Build on ARM, AnyCPU solution settings was actually using X64. EventStore#4129
  • Filtered $all subscription enumerator returns InvalidPosition when subscribing at an invalid position. EventStore#4131

Removed

Breaking Changes

  • Remove the external TCP API and related configuration options. EventStore#4113 and EventStore#4153
  • The following options have been removed:
    • AdvertiseTcpPortToClientAs
    • DisableExternalTcpTls
    • EnableExternalTcp
    • ExtHostAdvertiseAs
    • ExtTcpHeartbeatInterval
    • ExtTcpHeartbeatTimeout
    • ExtTcpPort
    • ExtTcpPortAdvertiseAs
    • NodeHeartbeatInterval
    • NodeHeartbeatTimeout
    • NodeTcpPort
    • NodeTcpPortAdvertiseAs
  • The behaviour for filtered $all checkpoints has changed (EventStore#4131). Instead of receiving a checkpoint exactly after the checkpoint interval, a checkpoint will be issued at least once per checkpoint interval:
    • When live, checkpoints will still be issued after exactly checkpoint interval events.
    • When catching up, checkpoints will still be issued after exactly checkpoint interval events (except that the first checkpoint will be offset by one event).
    • When transitioning from catch-up to live, a checkpoint is issued.
    • When falling behind from live to catch-up, a checkpoint is issued.
