    2.13.0
	Compatibility notes:
	     * Drop support for versions of groff before 1.21 (released on 2010-12-31).
	Fixes:
	     * Fix `man-suffixed-extension` test failure when not using the GNU
	       hierarchy organization.
	     * Fix `-Wmissing-variable-declarations` warnings with GCC 14.
	     * Fix `-Wflex-array-member-not-at-end` warning with GCC 14.
	Improvements:
	     * Upgrade to Gnulib `stable-202407`.
	     * Support running the test suite against an installed package; this is
	       useful for systems such as Debian's autopkgtest framework.
    2.12.1
	Fixes:
	     * Fix excessive cleanup of `/var/cache/man` by `systemd-tmpfiles`.
	Improvements:
	     * `man` matches the display width more accurately to the configured width.
	     * Upgrade to Gnulib `stable-202401`.
	     * Mention `groff`'s `pdf` device in `man(1)`.
	     * Speed up `seccomp` filter slightly.
	     * Document how to format pages using italic rather than underlined text.
	Compatibility notes:
	     * Remove the obsolete `chconfig` tool for converting man-db configuration
	       files to the FHS.  This transition took place almost 25 years ago (at
	       least in Debian), so it's not worth keeping it around now.
