I have 7.10 for Mac installed, and I'm still seeing the problem with the extra newlines being inserted. It appears the problem is not with the Evernote editor but with the what Evernote is doing with the macOS clipboard when it detects text is copied to the clipboard. I'm seeing this problem with extra newlines when I'm trying to copy and paste lines of text between MacVim and Excel, not involving Evernote in any way. If Evernote is running, I have the newline problem. If Evernote is not running, I don't see the newline problem, at least in my 30 min of testing with Evernote not running. But I haven't had the time to run and document a series of comprehensive tests to figure out all the edge cases.
