proftpd-dfsg (1.3.1-3) unstable; urgency=low

    not that useful.  It was wrongly compiled in as a DSO module, anyway.
    A configuration option --enable-nls should be used instead.

    (closes: #451747, #451090, #457178)
  * Commented out stacktrace support at configuration time.
  * Properly moved to debhelper compatibility 5.

              This is a GPL2 or later program.
  * [Lintian] Spelling error adviced->advised fixed in README.Debian.
  * Added missing --oknodo at daemon startup in proftpd.init.
    (closes: #455562)
