Juliaup gui?

I saw that with 1,13 release, Juliaup was coming with a GUI. And when I take a look, this is documented in Juliaup GitHub. However, I am using Juliaup 1.22.3 and selfupdate stay on this version. Then no gui is found. When will be the new Juliaup release be released ? Or is there a way to install the gui separately ? Thanks,
