Event Store 5.0.3 Changelog

Important Bug Fixes

  • #1971 - (Core Database) Persistent Subscriptions: Always remove completed events from all connections to prevent outstanding messages from building up in the connection queues
  • #1998 - (Core Database) Persistent Subscriptions: Retry the load checkpoint read if the read expires.
  • #1990 - (Core Database) We have fixed a bug in our intermediate index cache.


  • #1991 - (Core Database) We have provided the ability to configure the connection queue size threshold. There are scenarios where a client might run into the maximum connection queue size. A likely scenario where this might occur is when a client is overwhelmed by a large number of events being ingested into Event Store and then being delivered to a subscription.


  • Release of Amazon Linux 2 and Oracle 7 packages
  • Fixed issue on Amazon Linux package where manual changes to the EventStore configuration file would be overwritten when the node starts up

How do I provide feedback?

We appreciate any feedback via either GitHub Issues or forum.
