From Guns.com:

New for 2024, Glock is starting to evolve its 5th Generation offerings deeper into its subcompact lines, with the .45 ACP G30 and 10mm G29 tapped as the next two on the list, joining the 9mm G26 and .40 S&W G27.

The biggest updates among some 20 modifications from the old Gen 4 standard to the newer Gen 5 include deleting the finger grooves in favor of a straight grip, adding front slide serrations, an nDLC finish, ambidextrous slide stop levers, and an enhanced Glock Marksman Barrel.
