            The CRM supports both Documenso 1.13.x (v1) and 2.x (v2). v1 is the default for
            backwards compatibility. v2 is recommended for new ports and unlocks the features below.
            Switching versions does <strong>not</strong> require any code changes - version-aware
            client methods pick the right endpoint per port. Switch, save, then run the
            test-connection button to confirm the chosen instance is actually on the matching
            Documenso version.
