Vault Enterprise: Change to default replication behavior in 1.13

This is an informational announcement regarding a change in the upcoming Vault 1.13 release. No user action is required.

In Vault 1.12, we provided a fix to reduce the impact of the merkle-diff/sync process to Vault’s replication. This fix was disabled by default. In Vault 1.13, we will enable this fix by default for users of integrated storage. We expect to also enable the fix by default for users of Consul storage 1.14+, after some additional validation currently in progress.

The fix is incompatible with Consul storage for Consul versions prior to 1.14.

Please keep in mind other Consul 1.14 considerations, if you’re running Consul on Kubernetes.
