KDE's website for KDE Linux has been updated to reflect this https://kde.org/linux/ <-- That is no longer the old site, claiming it was still in development.
However, if you visit the download page, they still claim it is the testing build. 
https://kde.org/linux/install/
A bit of conflicting information.
