The GTA project made the initial public releases: libgta version 0.9.0 and gtatool version 0.9.0.

Both packages are fully functional. The plan is to make corrections and changes during the 0.9.x series where necessary. At the time of the 1.0 release, both the GTA file format specification version 1 and the libgta API/ABI will be frozen, and all future releases will be backward compatible if at all possible.
