The FSF has substituted the phrase “modified works” in place of “derivative works” in v3 of the license, yes, but not to narrow the definition - the intent was to broaden the definition to cover additional classes of modification.

From the FSF’s licensing FAQ:

> Where's the line between two separate programs, and one program with two parts? This is a legal question, which ultimately judges will decide. We believe that a proper criterion depends both on the mechanism of communication (exec, pipes, rpc, function calls within a shared address space, etc.) and the semantics of the communication (what kinds of information are interchanged).
