What is the difference between 2555T and 2555?

US Expat living as permanent resident overseas. I pay foreign income taxes.

Every year I file a 2555. 

This year, TurboTax (TT) asked for me email because they haven't uploaded 2555T.

I'm confused. Is this the new version of 2555?

OR

Is it some other weird form that I don't need and should continue to use 2555, and delete 2555T?
