stabilization of v0.1.73

[Vojtech Polasek]

Hello all,

The release of Content version 0.1.73 is scheduled for May 10, 2024.
As part of the release process, a stabilization branch was created.
Issues and PRs that were not solved were moved to the 0.1.74 milestone.

Any bug fixes you would like to include in release 0.1.73 should be
proposed for the *stabilization-v0.1.73* and *master* branches as a 
measure to avoid
potential conflicts between these branches.

The next version, 0.1.74, is scheduled to be released on August 09, 2024,
with the stabilization phase starting on July 29, 2024.

Regards,

Vojtech Polasek
