Version 5.0.8 has been released which contains a number changes and bug fixes.
Event Store 5.0.8 is out!
This release contains some important bug fixes related to TCP connections for both the server and the .NET client. The fixes bring an overall improvement to the stability of subscriptions.
It is available for the following operating systems:
- Ubuntu 18.04
- Ubuntu 16.04
- CentOS 7 (Commercial version)
- Amazon Linux AMI (Commercial version)
- Amazon Linux 2 AMI (Commercial version)
- Oracle Linux 7 (Commercial version)
- When a long running node in a cluster has observed a large number of elections, the SendViewChangeProof that is scheduled could cause cluster instability.
- Always load up partition state which could previously have caused stale state’s to be observed.
- Don’t auto resubscribe TCP catchup subscriptions which could potentially cause duplicate events to be observed. It is now expected that users will resubscribe their subscription in
SubscriptionDroppedto recover from TCP connection losses.
- Introduce the ability to clients to gossip over TLS when using gossip seeds.
- Provide the ability for the Event Store 5.x TCP Client to handle the old and new cluster terminology. The terminology changed from Slave to Follower and from Master to Leader.
Please consult the Changelog for more details.
