FT8CALL's creator, Justin KN4CRD, has been very busy. There is a new version of this new QSO-friendly data mode with new features and a change of name - the mode is now known as JS8 and the program is named JS8Call. The name change seems to have been at the request of FT8's creators Franke & Taylor.

New features include message compression, that increases throughput to around 15 WPM, selective and group calling and a nifty way to adjust your time if away from an accurate time reference (eg at a DX Picnic). You can get the program here: https://groups.io/g/js8call/wiki/Download-Links
