WSJT-Z is a clone of WSJT-X software by Joe Taylor K1JT (https://sourceforge.net/projects/wsjt/).
CHANGELOG is available on the Files page (https://sourceforge.net/projects/wsjt-z/files/).
It started out as an automation project, but recent versions focus on providing additional functionality to an already great tool.
