Yes, seems it needs to be updated a bit. Most new additions are listed in the changelog.txt file in the Game Guru folder of your install.
Some might also be readable variables from the global.lua file which lists the current commands attached to the engine, and some at the bottom which are AGK commands for sprites and mouse stuff.
If you tell me which script the mentioned one from you, I will see if I can find that answer for you.
