Nice! I don't know if this is new since I last used it or if I just didn't know about it.
I imagine photoshop has had it for a long time. I do raw photography very sparingly and barely know photoshop. Literally one of the first thing I wanted to do was batch operations on a set of photos in which the lighting and camera setting were exactly the same. A quick Google revealed it is frequently used.
Photoshop hasn't even existed for a long time yet.
You can select a group of operations you did in your editing history and turn them into an Action, with parametrization support.
You can then batch apply an Action to a bunch of files.
