The purpose of UPDATING is to document changes that break backward compatibility, i.e. running old binaries on a newer world. What happened here is that you tried to run newer binaries on an older world, an issue of _forward_ compatibility, which we've never promised. Besides, an entry in UPDATING wouldn't have helped you since your source tree predated the change that would have added it. DES --=20 Dag-Erling Sm=C3=B8rgrav - des@FreeBSD.org
