Not sure how I missed this in my notifications. Thanks for the PR @keewis ! LGTM

Hmm . i have no idea why CI is failing here with a cache miss even though the cache is definitely defined?

[VeckoTheGecko]

Let me know if you have any ideas @keewis

Btw, the edits I pushed here were to ensure that manifest-path was an optional input.

I have given you push access here. Feel free to push edits and merge if you'd like

I think the problem is that the caches can't be deleted by tests run on a branch on my fork. Let me try clearing the caches manually.

[keewis]

well, looks like either pixi.lock and ./pixi.lock are treated differently, or we need special permissions to clear the caches in CI. Either way this works now, so you can go ahead and merge now (and if possible a release would also be nice)

if possible a release would also be nice

Done! Thanks for the PR
