TCM/ECM updates associate with ITB13-019a and ITB13-056a

Have a 2013 G37S sedan. Took it to the dealer for 90K mile service. Asked them to check for any ECM/TCM updates. Got a call back stating there was both a ECM and TCM update available.

Paperwork says they updated the following:
ECM (ITB13-056a):
New Version: 23710-3LW2C
Old version: 23710-3LW2A

TCM (ITB13-019a):
New Version: 31039-X986D
Old version: 31039-X628D

From the description in the Service Bulletin, these updates look benign.

Does anyone else with a 2013 G37 have any experience with these updates?

Thanks in advance!
