Just tried v4.3. It's mainly "cloud oriented", compared to v3 and I don't need that. Luckily, you still can use it offline and for anyone starting with v4, there's no reason using v3 instead. Unfortunately, if you have made a lot of scores using v3, and still use them, there are chances that the new engraving rules of v4 will mangle your old scores if you follow their advice to reset positions... If you don't, there might be some items slightly misplaced but it doesn't look that bad. The real issue is that if you open multiple files, each one will open in a duplicate version of the app! 😲 So, working with ten scores together will eat a lot of cpu and ram for nothing... That was not the case with v3.
