    - man: Move parallel-safe note from dpkg-buildpackage -j option to
      --jobs-force.

    - start-stop-daemon: Cast struct sockaddr_un to struct sockaddr on bind()
      call.
    - lib: Stop using register keyword.
    - libcompat: Remove unused arguments from ngettext() fallback macro.

    - libdpkg: Add new multi-threaded xz decompression support. Closes: #956452
    - libdpkg: Pass -T+1 instead of -T1 to xz when compressing.
    - libdpkg: On threads-max > 0 pass --no-adjust to xz to force threaded
      mode.
    - Use hyphenated multi-threaded in text.
  * Build system:
    - Consider lib and utils prefixes as internal in gen-changelog.
    - Fix m4 files coding style.
    - Include <stdio.h> for printf() usage in __progname check.
  * Packaging:
    - Require liblzma >= 5.4.0 for multi-threaded compressor support.
    - Clarify versioned dependency rationale comments.
    - Add pkgconf as main Build-Depends alternative to pkg-config.
  * Test suite:
    - Skip deb-format tests if required compressors are not present.
    - Use a custom dpkg database directory for dpkg-buildpackage tests.
    - Switch Dpkg::Source::Package test to use test_needs_openpgp_backend().
    - Skip deb-format tests if gzip is not present.
    - Skip dpkg-source tests if xz is not present.
    - Use the PERL detected at configure time in autotests.
    - Use perl instead of yes+dd to generate a data-file for deb-split.
