@jaimergp This is ready and tested, PTAL. CI failures are unrelated.

This looks good. Let's discuss the pinning item briefly and then we can make a decision.

@jaimergp Updated, PTAL.

The only concern I have is that the library version bounds might not be strict enough. The authors introduced a breaking change between 2.5.4 and 2.6.0. But this can also be updated later if we run into problems.

Yea, I saw that, but hopefully they have learnt from that oversight. Also this kind of comment makes me believe they are being more careful now and not too keen on breaking anything else.

Just one more thing.

Also, since this adds a new dependency, what's the process for letting the release manager know there are new deps to be added to the conda recipe? Will they look at a specific file? Maybe pyproject.toml also needs adjusting?

[nkaretnikov]

@jaimergp I've added platformdirs to pyproject.toml. I've never released conda-store, let's ask Tania.

@trallard How do new dependencies affect the release process? Anything to do besides updating pyproject.toml and yaml files? I've read release.md -- just making sure.

[trallard]

Only the pyprojecr.toml needs updating
