Does an in-depth changelog exist? I've noticed there are a few subtle differences, for example between 2.7.2 and 2.7.6 like how if you exit the song editor it'll bring the currently playing pattern back into the pattern editor, rather than dumping you out to a blank pattern.. this isn't documented anywhere so I was tearing my hair out trying to get the song mode to be useful for live gigs on my 2.7.2 cart. It'd be nice to know what else I'm missing out on!
