We’ve just released NServiceBus.RavenDB 6.5.1.
#662 Log an error if the cluster topology has more than 1 node
How to know if you are affected
If you are using RavenDB 4 or above with a cluster of 2 or more nodes, you are affected. Read Cluster configurations with multiple nodes not supported for more information.
When to upgrade
This patch release is only intended to alert users to the issue with RavenDB clusters. The only change to the code is to emit an error in the logs to avoid introducing a breaking change in a patch version. Read the documentation linked in the previous section to fully understand the problem.
