If so, it seems the me that, at runtime, it would be reasonable to exclude new version-dependent features if either the $too_old flag is set or the version number is lower than the feature needs. It would also be reasonable for sa_update to report the exclusion since that serves to remind the sysadmin to upgrade. Martin
