Official pie menu dropped on Today´s 2.81?

What happened? It was working on yesterday´s version and today I see the warning message that the script is not supported any more?
And what´s up with “CTRL+S” being in a pie menu?
ALT+SPACEBAR is the current assigned pie menu to transformation tools.

I need the CTRL+SPACEBAR to toggle between my transformation tools in a glimpse.
How can I restore it back, please?
Urgent help!
