CBMPrgStudio v4.0.0 by Arthur Jordinson (Released October 2022) - It's been over two years between releases (v3.14.0 being previous), but it was well worth the wait!  If you do any kind of coding for the Commodore 64, VIC-20, Commodore 128, Commodore 16, Commodore Plus/4 or Mega 65, then you're going to want to check out this development environment. There are so many cool features and capabilities that I'm not going to bother listing them.  You need to head over to https://www.ajordison.co.uk/ and see for yourself.
