Hi Ray,

you’re right, the Cycles tests need to be updated. They need to make use of the new fluid modifier.
Sergey pointed this out to me right after (within 12h) I landed the commits, i.e. the issue is known.

So yes, blame it on me, I overlooked this part. I will look into this as soon as possible.

I agree that this is not ideal. But apart from better commit messages, how can we do better at this time?

Happy new year and best wishes,
