I see the notes for version 5, but where is version 5. All I see is version 4
Go to:
chrismaltby.itch.io/gb-studio
Then go to: “Download Now”> “No Thanks, Just Take Me to the Downloads” (or you can donate if you want)> You will see a pop-up, then press the “Download” Button on the top of the list (or the one second from the top). These are the 32 and 64 bit versions with the installers.
