fyi: datasets created with version v0.14.25 are not backward compatible with v0.14.24

[erjel]

I cannot read datasets created with version 0.14.25 onward with version 0.14.24.

Error message:

I will update my environments to the newer versions now, I just want to make you aware of the breaking change.

@erjel Thanks for letting us know.

On an unrelated note, we recently switched from poetry to uv for Python package and environment management. Maybe you would like to check it out as well. PR
