    (Closes: #838296)

    warning from apt about it being unsuitable for scripts.

apt-file (3.0~exp) experimental; urgency=medium

  * BACKWARDS INCOMPATIBLE CHANGES:
    - diffindex-download and diffindex-rred has been removed!
      (Closes: #788780)
    - apt-file now exit with non-zero exit code when the
      query results in no matches.  (Closes: #505222)
    - apt-file no longer supports "personal" caches on its
      own.
    - apt-file show (a.k.a. list) now looks up only an exact
      package name by default.  To retain the previous
      behaviour, please use the new --substring-match option.
    - Special uses of "-a" to search in Source packages or
      udebs have been replaced by "--index-names".
    - apt-file now uses "gnu-getopt" option style parsing.
      Notably this means that "+" cannot be used for options
      any longer.
  * Rewrite apt-file to use apt's new acquire system.  By using
    apt, apt-file:
    - makes apt refresh the Contents files.
      (Closes: #476401, #594879)
    - now understands "non-release" lines.  (Closes: #297707)
    - no longer sends "double" requests.  (Closes: #663417)
    - now validates downloads correctly.  (Closes: #515942)
    - can resume downloads (like apt).  (Closes: #594879)
    - now respects Acquire::http::Dl-Limit.  (Closes: #525631)
    - supports deb822 sources.list file.  (Closes: #740978)
    - supports tor+http protocol (Closes: #764349)
    - supports "mirror" protocol (Closes: LP: #888316,
      LP: #1156717, LP: #1395988)
    - respects APT proxy settings (Closes: LP: #817517,
      LP: #767061)
    - now silently accepts that not all mirrors have Contents
      files (Closes: LP#567895, LP#619659).
    (Closes: #752292)
  * Expand the README a bit to give a quick introduction to
    apt-file and indices.
  * Rewrite the manpage from docbook to POD format.
  * Update dependency lists due to the above rewrites.
  * Remove the old apt-file cache on upgrade.  This means that
    users will have to run "apt update" after upgrading.
  * Update the "is-cache-empty" and "do-apt-file-update"
    scripts.
  * Rewrite d/rules to use debhelper "tiny" and bump the
    compat level 9.
