propellor (0.8.1) unstable; urgency=medium

  * Run apt-get update in initial bootstrap.
  * --list-fields now includes a table of fields that are not currently set,
    but would be used if they got set.
  * Remove .gitignore from cabal file list, to avoid build failure on Debian.
    Closes: #754334
