When did these changes take place?

Photobooth is a Google Camera feature introduced on the Google Pixel 3. The feature automatically takes photos when it detects smiles or funny faces in the frame. Although we don’t exactly know what kinds of improvements will be made to the feature, it looks like Google might introduce some under-the-hood changes. Throughout the code, we spotted checks to see if “Photobooth2019” is supported, in comparison to just “Photobooth,” meaning that this is an update to the existing Photobooth feature.
