greed (3.7-1) unstable; urgency=low

  Newest score files (since version 3.7) of greed are not compatible with
  old score files (< version 3.7). If you upgrade to greed 3.7-1 from a
  version lesser than 3.7, and you have an score file then it will be
  moved to /var/games/greed/greed.hs.dpkg-old in order to preserve your
  scores.
  Please be aware that in the above case any file with name
  greed.hs.dpkg-old in the greed directory will be overwritten during
  the upgrade.
  Downgrade: If greed (>=3.7) is installed or was removed, but not
  purged, then you must purge the package before installing any version
  lesser than 3.7.

  As expected if you purge the greed 3.7-1 package all the score files
  will be deleted including greed.hs.dpkg-{old,new}.
