MC18 and MC19 can't use the same library. MC19 uses a newer format that MC18 won't be able to read.
Different libraries is not my problem, i think. I use MC 18 with the same paths, same files as i use them now in MC19.
When i'm testing some new features, or do some tagging in MC 19, what is the standard behaviour of MC 18.
Of course i know it can't overwrite tags, that don't exist in MC 18, like the new R128 tags. I mean all the others (Name, Year, Cover,.....)
That would be my holocaust, if everything i test and change (tags) in MC 19 now, is lost when i use MC 18 then.
Or easier said, what's the standard behaviour of MC 18 & 19 when they startup and check library (files) and they find differences in library and file tags itself. Do both overwrite the file tags, or update their library with the new values, or do nothing until the user updates library from files or the other way round, manually.
Sorry, it's the first time i use two MC Versions with the same filepaths, but i couldn't wait to test new volume leveling.
Normally i start with the first official stable beta release, and then uninstall the older version.
One Topic Question:
Do MC Team change R128 further, like last update (adding DR Analyze)? I analyzed many Files yesterday and now i have to analyze again. Or only bug fixing now?
