My current version (from "git describe") is "1.22.4-3311-g37ef8583".
There are two tmac-files that test for version "1.23" or later, so they abort the processing. I do not have a ".tarball-version" file. If I create it with content "1.24.rc1" the created versions are always the same as that. File "configure.ac" contains: AC_INIT([GNU Troff],[m4_esyscmd(build-aux/git-version-gen --prefix "" .tarball-version)],[http://savannah.gnu.org/bugs/?group=groff],[groff]) The latest commit with a tag is commit c05b538c504106d55b81caa6400ea80797f03775 (tag: 1.23.0.rc1) Author: Bertrand Garrigues <...> Date: Wed Nov 11 01:58:55 2020 +0100 -- Bjarni I.
