Version Check has not yet been added to master branch

[DHaussermann]

We don't have a version bump PR for Jira yet, but I have done some testing from the master brach for the release. That said, I noticed that no PR was ever up to bump the minimum server version to v6.5.0

This should be in place to prevent the plugin from running on older server version as per previous discussions.

Maybe @levb can confirm my understanding of the expected behavior here.

AFAIU, we do not require any new APIs from the server, merely exposing new hooks, therefore increasing the server version was not strictly necessary. I'll leave it to @hanzei to decide if we should update as a matter of policy.

Yes, we should update the minimum server version to follow the policy we set our self.
