I’m using the Nanowrimo preview of 2.0. Not sure if this is a bug in just the preview version or not, but when I tried to open a 1.0 file in 2.0, it told me it needed to update the file, and that it would make a backup.
The only issue is that the new file and the backup were both blank. It had erased everything from the original file.
Thankfully, the file I was trying to import was backed up in several places, but it might be something worth looking into. I’d hate to see someone lose their work.
Other than that, I’m loving the new version.
