nmh (1.3-1) unstable; urgency=low
  This release changes the db library dependency to an unversioned libdb,
  which will build using the most recent libdb available on your
  platform. This may cause an odd error from slocal if the version of
  libdb has changed from the last upload, as in bug #186412:

  slocal: unable to perform dbm_open on /home/user/Mail/.maildelivery:
  Invalid argument

  This error is correctable by removing the file called .maildelivery.db
  your Mail/ directory; this file is the list of message ids used by
  supressdup.
