--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> --- 10.3.1 is a version used by gcc snapshots in between 10.3.0 and 10.4.0 releases. As 10.3.0 has been released less than a week ago, 10.4.0 will likely be released next year (or in December this year), just check https://gcc.gnu.org/releases.html#timeline for the past release dates.
