AU Plugin Version in Logic Pro X

That’s interesting, I didn’t see that when I was testing yesterday. Which Plist properties are you updating? I think I was seeing the desired behaviour when changing the “version” key in the “AudioComponents” part of the plist (i.e. not the CFBundleShortVersionString or CFBundleVersion keys). Are you definitely modifying the correct property? If so, can you provide any other relevant info so that I can try to reproduce the issue (e.g. platform (intel/arm), OS version, Logic version)
