Since when was 'Workspace:FindPartsInRegion3' deprecated?

Just was creating some simple code to change some values in a player when they are in a region.

I noticed that the prefill text/the thing that gives you options to pick when scripting had FindPartsInRegion3 strikes out. After doing some searching It is deprecated. I haven’t used region3 this function in a while but when did it get deprecated?

Are their any alternatives that I should use now, I don’t want to use this incase it breaks in the future even though it is currently working now.
