A new Xperia Z C6603 firmware has been rolled out with build number 10.3.1.A.1.10 firmware on France’s Orange carrier. Previous global update seen on Xperia Z’s both variants C6603 and C6602 was 10.3.1.A.0.244 which was a major bug fixing update.

It seems it is a carrier based update and 10.3.1.A.1.10 firmware update ( android 4.2.2 ) is only available with “Orange” Carrier, we don’t see any such update notification on our Xperia Z C6602 here in India. It seems a minor bug fixing update only available over PC Companion/SUS and Bridge.
