How to install v3.0?

I’ve enabled installation of latest development builds according to
Platformio menu does not show the expected Platformio → Upgrade Platformio. Instead. using Platformio → Upgrade Platformio CLI installs the latest 2.0 dev version, but not 3.0.

Any hint appreciated.

See my answer here:

I’ll inform in #announcements category when it is ready for testing.

Being patient then, or trying to :wink: Excellent work btw!
