Isn't it great when build systems add more validation without caring about backwards compatibility?

[Comment 2 Michał Górny 2025-01-06 11:42:13 UTC]

Oh wait, it's the other way around.  Your version is severely outdated.

[Comment 3 Alarig Le Lay 2025-01-06 11:45:17 UTC]

Ah indeed, “fun” that portage didn’t try to update dev-python/hatchling before dev-python/attrs. Sorry for the noise :/
