Sam has released Sonic Pi 4.5.1 with installers available for Mac OS, Windows 10/11 and Raspberry Pi OS (64 bit Bookworm version) on sonic-pi.net
This is a maintenance release, primarily to help the windows install and problems with certain locale settings. Both Windows and Mac are switched to ruby 3.3.1. The RPi install still uses the built in ruby 3.1.2
There is a corrected bug in uncommenting (only remove outer comment)
