Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

Seems to work with conda-forge/conda-smithy#1751

[xhochy]

One caveat: This will break automerge as that will rerender with the conda-smity release version.

[pavelzw]

Should we wait until conda-forge/conda-smithy#1751 is released?

[xhochy]

If @pavelzw and @0xbe7a commit to rerender with the conda-smithy PR until it is released, I'm fine with merging this.

Note for the reader: I work together with them ;)

[0xbe7a]

Sure, if the conda-smithy PR takes longer than a couple of weeks to merge we can also just setup the swap by hand and not have to manually rerender for eternity.
