It looks good to me. Maybe add the MWE to tests?

[bgroenks96]

Ok, is the revision in Project.toml automatically updated?

[yebai]

I don't think so. You need to bump it manually, too.

[bgroenks96]

Ok so turns out that wasn't the fix, I had to add dispatches for output_length and transform. Please take a look and then run the tests again when you're ready.

[bgroenks96]

I am also running the tests locally so we'll see if these changes break anything. I tried to be specific with the dispatches.

I don't think this test failure is related to this PR...? but I am not sure from first glance.

Agreed that it seems not related to this PR

[bgroenks96]

FWIW the tests passed locally for me.

Is anything else needed before merging?

Thanks, @bgroenks96 -- a random CI failure went away after a second CI run.
