"Downcast alphas_cumprod: True" in Override Settings?

[pw405]

After the two recent updates, I've noticed whenever I use the blue arrow to populate my previous txt2img parameters, or use Infinite Image browsing to send an image to Txt2Img, there is a new note added in the Override settings that says: Downcast alphas_cumprod: True.

I have only previously seen this override settings field be populated if I had used Clip Skip on a prior image. It doesn't seem to be causing any issues, I've just been removing it. Curious about what it means is all. Anybody happen to know?

Slightly changes all image generation. The PR changes alphas_cumprod to be never be fp16 unless the backwards compatibility option is enabled. Backwards compatibility option is "Downcast model alphas_cumprod to fp16 before sampling", and it's automatically enabled when restoring parameters from old pictures (as long as they have Version: ... in infotext).
