+Subject: [PATCH] Use correct versions when binding globals
+
+Changes to protocols aren't forward-compatible. It's not possible to use
+version n+1 when a client has been designed to work with version n. For
+instance in wlr-screencopy v5 a new event has been added. Binding to
+version 5 without upgrading the client leads to libwayland errors
+because libwayland doesn't know how to handle the event.
+
+The client needs to maintain its own version requirements.
+
