E-TTL or E-TTL II with 6D

I am looking to upgrade to a full-size sensor, most likely the 6D. My only Canon Speedlight is an E-TTL (380EX). Will it function with the 6D, or do I need to get a new E-TTL II unit?

E-TTL and E-TTL II are metering functions of the camera body, not the flash. You don't need a new flash to get the "advantages" of E-TTL II.

Absolutely right: Except, the later flashes do have some functions to take advantage of the newer bodies.

Nothing to buy a new flash for IMHO but interesting from a tech point of view:
The flashes recognise a crop camera body so zoom differently when attached
They also transmit WB information to the camera
There's other issues too, but it was a long time ago and nothing important enough for me to retain.
