Debbugs upgrade notes
+=====================+
+From 2.4.1 to 2.4.2
+-------------------
+
+The file format used to store the status of a bug (package, severity, etc.)
+has changed; it is now in an RFC822-like format in order to be more
+extensible, and is written to .db files rather than the old .status files.
+Before accepting any mail with the new version of debbugs, you must run the
+'debbugs-upgradestatus' program over your bug spool. The old .status files
+will be left intact, and will continue to be written in sync with the .db
+files for compatibility with external tools.
