Require a minimum client version

Helix Core Server offers a mechanism to control which versions of client applications are able to connect to it.

To require a minimum version, set the configurable minClient to the appropriate revision.

You can also set the minClientMessage configurable to the error message that you want to be displayed when users attempt to connect to the server from a client application that needs to be upgraded.

For example:

$ p4 configure set minClient=2019.1
$ p4 configure set minClientMessage="Please upgrade to 2019.1 or higher"
