I=E2=80=99m not a newcomer but I find it limpid: I think it immediately sho= ws that this is about version changes and when they happened. Maybe it could be decluttered a bit by using shorter date strings (like =E2=80=9COct. 1st=E2=80=9D instead of =E2=80=9C2020-10-01 18:42:00=E2=80=9D= ). BTW, when looking at /output-history, the commits in =E2=80=9CFrom=E2=80=9D= and =E2=80=9CTo=E2=80=9D can be a bit confusing. Take: https://data.guix.gnu.org/repository/1/branch/master/package/openmpi/outp= ut-history I see =E2=80=9CTo=E2=80=9D pointing to , a commit that changes =E2=80=98mpd=E2=80=99, which =E2=80=98openmpi=E2=80= =99 doesn=E2=80=99t depend on; this is completely bogus. However, the next =E2=80=9CFrom=E2=80=9D points to the r= ight commit: . It=E2=80=99s surprising that =E2=80=9CTo=E2=80=9D and the immediately follo= wing =E2=80=9CFrom=E2=80=9D are not the same. WDYT, Chris? Thanks, Ludo=E2=80=99.
