I had my 2015 GC in for warranty work (door hinge) and they also did:
Software Flash for TCM (Flash Software 1)
Software Flash for PCM (Flash Software 2)
Software Flash for TPM (Flash Software 3)
SET PRmeters
What are these software flashes for?

Those are transmission flashes. Just a word of caution. Don't have them done unless you are actually experiencing a problem. Often times they will create a problem where there wasn't one.

Too late. I wasn't having any problems and they applied the flashes anyway.

Just out of curiosity. What was the issue with the door hinge?

They had to replace the lower hinge on the driver door. It was making a crack crack noise at each stop position when opening and closing the door.
