debhelper (8.9.12) UNRELEASED; urgency=low
+ * Debhelper config files may be made executable programs that output the
+ desired configuration. No further changes are planned to the config file
+ format; those needing powerful syntaxes may now use a programming language
+ of their choice. (Be careful aiming that at your feet.)
