+-Update to version 13.5.2
+   * dh_installsystemd: Revert change to deploy systemd files into
+     usr/lib/systemd.  (Closes: #993316, #993759)
+   * dh_installinit: Ditto.
+   * dh_systemd_enable: Ditto.
+   * dh_systemd_start: Ditto.
+   * SequencerUtil.pm: Remove duplicate "-a" option to some commands.
+     Thanks to Christoph Berg for reporting the issue.
+     (Closes: #971761)
+   * dh_installdeb: Revert the change to rewrite `rm_conffiles` into
+     `remove-on-upgrade` due to it causing bugs in non-trivial cases.
+     (Closes: #994919)
+   * dh_installtmpfiles: Add missing option name in POD documentation.
+   * cmake.pm: make it possible to override dh provided ctest arguments
+   * cmake.pm: Add missing import which broke cmake related builds.
+     Thanks to Boyuan Yang for reporting the issue.
+     (Closes: #993345)
+   * dh_installdeb: Install debian/conffiles in compat 12+ again
+     (undoing the compat 12 change saying dh_installdeb would ignore
+     this file).  The file can now be using for the activating the
+     `remove-on-upgrade` feature from dpkg 1.20.
+   * dh_installdeb: Automatically rewrite `rm_conffiles` into the
+     new `remove-on-upgrade` feature from dpkg when possible.
+   * cmake.pm: Pass `ARGS+=--verbose` to make when running tests
+     in the cmake+make variant except when "terse" is in
+     DEB_BUILD_OPTIONS.  Thanks to Paul Wise for the suggestion.
+     (Closes: #992623)
+   * python_support.pm: Remove obsolete dh addon.  It did nothing
+     but warn and nothing used it anymore.
+   * dh: Document debhelper provided dh addon sequences.
+   * single_binary.pm: New dh addon ("single-binary") that explicitly
+     activates the "single binary" work flow, where dh_auto_install
+     uses debian/<pkg> as default --destdir when there is only a
+     single binary package.  It will error out if used in a
+     source package building multiple binary packages.
+   * dh: Activate "single-binary" addon by default in compat levels
+     up to and including compat 14 when the source package only lists
+     one binary package in debian/control.  In compat 14, emit a warning
+     when this happens implicitly requesting users to explicitly enable
+     or disable the addon for single binary source packages to avoid
+     surprises in compat 15.
+   * dh_auto_install: In compat 15, remove special-case default for
+     --destdir for single binary source packages.  If the previous
+     default is desired, please use the "single-binary" dh addon or
+     explicitly pass --destdir to dh_auto_install.
+     (Closes: #971432)
+   * debian/control: Provide dh-sequence-single-binary.
+   * debhelper.pod: Document the dh_auto_install will change behaviour
+     in compat 15 for single binary packages and dh will warning about
+     that in compat 14.
+   * dh_assistant: New tool for assisting third-party tools.  At the
+     moment, it primarily supports introspection related features but
+     will hopefully be extended to support more use cases.
+     (Closes: #984900)
