FLAC3D now has a two-dimensional counterpart: FLAC2D. Some of the rationale for this is explained in the topic FLAC2D for FLAC 8.1 Users.

The programs share the same code base and, consequently, many commands and FISH functions are common to both. In this documentation, “FLAC” as a term always indicates both programs at once. Statements using FLAC will be true for both programs. The limited use of the names FLAC2D and FLAC3D occurs only when specifically indicating information that is solely applicable to one or the other.
