Side-Note:
The cadet-cli for this gives

This is cadet-cli version 5.0.1 (fix_coordinates_for_singleton_dimensions branch)
Built from commit d0b7e622f5a1df5c33c1aa46d4a4327d4860cbb0

Shouldn't it already be 5.0.2?

Shouldn't it already be 5.0.2?

Good point! I had also noticed it but thought that maybe this was a local issue. Should have written it down somewhere...

Running cadet-verification i saw that the crystllization tests are broken, chromatograohy tests still work. However that happened before the changes made on this PR.
Ill see if I can fix this and push the changes here to this branch since this should also be part of 5.0.3 :D

[jbreue16]

The version info is read from git as specified in the versioninfo.cpp.in and CMakeLists.txt, maybe this was lost during the shenanigans of the last release. v5.0.3 should automatically pull the correct information

CADET-Verification works fine now

[schmoelder]

yeah, if you run

git describe

it returns

v5.0.1-23-ga833ff7a

not quite sure why, though...

[jbreue16]

Is it worth looking deeper into this or should we just continue with v5.0.3, assuming that this is automatically fixed ?

[hannahlanzrath]

I assume it is connected to the complications of the last release. Since the ´cadet-cli´ of the actual release 5.0.2 shows the correct versions, personally I would just move on.

[schmoelder]

let's move on.
