Almost all popular AGS games fail to load citing new version requirements

[quicksand]

Using the Dec 27, 2018 pull of the latest setup script, I upgraded AGS (tested both binary and source).
The newly-installed AGS binary fails to open all 30+ of my AGS games stating they need to be developed using engine version 48 or 49.

According to AGS's github README.md, "Master branch contains AGS 4.x, which is currently undergoing refactoring/rewrite and may not be very stable. It is intended to support games made with AGS 3.4.1 - 3.4.2, but only if these do not use any legacy features. The 4.x engine should be reading savegames made with the 3.4.2 engine and above."

I modified RetroPie-Setup's ags.sh script to pull the "ags3" branch (3rd argument), and it now loads all 30+ games as shown here:

I would suggest sticking with the "ags3" branch (which is still receiving updates) in the ags.sh script, instead of tracking master until it's reported stable is and compatible with many of the popular AGS remakes out there.
