RS274D (pieces of)
    Legacy gerber (external aperture definitions), officially obsolete and not conforming

RS274X rev I4 
    Standard gerber until last year, some commands are deprecated

RS274X rev J1 a.k.a. RS274X2 
    Current standard gerber with attributes. Also drill tapes can
    'officially' be done in gerber, now (if someone supports them is
    another story...)

In short, yes, you are right :D
