Dear Maintainer,

libreoffice 7.2.3-1 had a broken changelog accidentially including
7.3.0~alpha1-6 changelogs and making 7.2.3-1 a "successor" of said
7.3.0~alpha1-6.
See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1000605

That was fixed in -2 - by removing said stuff, see
https://salsa.debian.org/libreoffice-team/libreoffice/libreoffice/-/commit/4ae0cd949473bd84702798c14d5d33d44895be64 -
but that never was corrected itself in the BTS.

See e.g. the broken version graph in
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=985867:
https://bugs.debian.org/cgi-bin/version.cgi?info=1;collapse=1;fixed=libreoffice%2F1%3A7.1.2~rc2-1;fixed=libreoffice%2F1%3A7.3.0~alpha1-1;absolute=0;found=libreoffice%2F1%3A7.2.1-1;found=libreoffice%2F1%3A7.1.2~rc1-1;package=src%3Alibreoffice

The 7.2.x's being a successor of that alpha1-6 is wrong.

Proper history (more uptodate first is):

libreoffice (1:7.2.5-1) unstable; urgency=medium
libreoffice (1:7.2.4-3) unstable; urgency=medium
libreoffice (1:7.2.4-2) unstable; urgency=medium
libreoffice (1:7.2.4-1) unstable; urgency=medium
libreoffice (1:7.2.3-2) unstable; urgency=medium
libreoffice (1:7.2.3-1) unstable; urgency=medium
libreoffice (1:7.2.2-1) unstable; urgency=medium

for the 7.2.x packages (sid until today)

and

libreoffice (1:7.3.0~rc2-2) unstable; urgency=medium
libreoffice (1:7.3.0~rc2-1) experimental; urgency=medium
libreoffice (1:7.3.0~rc1-2) experimental; urgency=medium
libreoffice (1:7.3.0~rc1-1) experimental; urgency=medium
libreoffice (1:7.3.0~beta1-4) experimental; urgency=medium
libreoffice (1:7.3.0~beta1-3) experimental; urgency=medium
libreoffice (1:7.3.0~beta1-2) experimental; urgency=medium
libreoffice (1:7.3.0~beta1-1) experimental; urgency=medium
libreoffice (1:7.3.0~alpha1-6) experimental; urgency=medium
libreoffice (1:7.3.0~alpha1-5) experimental; urgency=medium
libreoffice (1:7.3.0~alpha1-4) experimental; urgency=medium
libreoffice (1:7.3.0~alpha1-3) experimental; urgency=medium
libreoffice (1:7.3.0~alpha1-2) experimental; urgency=medium
libreoffice (1:7.3.0~alpha1-1) experimental; urgency=medium
libreoffice (1:7.2.2-1) unstable; urgency=medium

(for the 7.3 packages, experimental and sid starting from today)

On IRC you just said:

22:30 < dondelelcaro> _rene_: currently there's not a way to manually change the version graph once it's been uploaded. It assumes that
                      what was in the changelog was correct. If you file a bug against bugs.debian.org, I can manually adjust what the
                      version tree thinks is reality
22:31 < dondelelcaro> (well, not a way for anyone besides owner@ to, anyway)
22:31 < dondelelcaro> (the problem is indeed that libreoffice (1:7.2.3-1) unstable; urgency=medium
22:32 < dondelelcaro> (the problem is indeed that libreoffice (1:7.2.3-1) unstable; urgency=medium was uploaded with (1:7.3.0~alpha1-6)
                      as the immediately preceeding version)

Please do adjust the version info :)

Regards,

Rene
