The following is quoted from ARRL News:
The WSJT Development Group has announced the “general availability” release of WSJT-X version 2.1.0. This major upgrade formally introduces FT4 as “a finished protocol for HF contesting.” Users have been advised to discontinue using any “release candidate” (beta) versions of the software that WSJT-X version 2.1.0 supplants. The latest edition of the popular digital software suite also includes improvements and bug fixes in several areas, including FT8. The list includes:
- FT8 waveform generated with GMSK and fully backward compatible
- User options for waterfall and spectrum display
- Contest logging
- Rig control
- User interface
The WSJT-X Development Group is providing a separate WSJT-X version 2.1.0 installation package for 64-bit Windows that offers significant improvements in decoding speed.
A detailed list of program changes since WSJT-X version 2.0.1 is included in the cumulative release notes. Upgrading from earlier versions of WSJT-X should be seamless, with no need to uninstall a previous version or to move any files.
Installation packages for Windows, Linux, and Macintosh are available.
