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.

Gentle ping @conda-forge/blas; planning to merge on the weekend if there are no comments.

I am not sure if this is the cause, but the following code started throwing an error after we did a conda update that included this version of openblas:

If you update to the latest SciPy build on conda-forge (following conda-forge/scipy-feedstock#268) or downgrade to OpenBLAS 0.3.25 you should be okay I think

Thanks. Scipy 1.12 does solve this.

With the merge of conda-forge/conda-forge-repodata-patches-feedstock#642, this should now also be fixed for 1.11 and before

No news from the side of blis.

Asked in issue ( flame/blis#792 ). Sounds like they are still working out some kinks before doing a release

[jakirkham]

Looks like a new BLIS release should be coming out soon
