Package "dselect"

  dpkg (1.18.4ubuntu1.7) xenial; urgency=medium

  * Add Zstandard (zstd) decompression support for binary packages
    (LP: #1764220)
    - The changes to ./configure and *.in files were cherry-picked from a
      manual autoreconf run because the package build does not run
      autoreconf automatically and the full delta from autoreconf
      was very big.

  dpkg (1.18.4ubuntu1.5) xenial; urgency=medium

  * Apply patch from upstream to add frontend locking (LP: #1796081):
    - Add support for frontend locking. This makes it possible for frontends
      using this new protocol, to safely lock the dpkg database w/o risk of
      race conditions with other dpkg instances or frontends supporting the
      same protocol.
