I’m excited about the new changes in ardour 7, particularly when it comes to MIDI editing. Still, I am concerned about the breaking changes, especially after the move from version 5 to version 6 that forced every project to be converted. Is it safe to open old projects with the new version? I couldn’t find anything in the release notes regarding this.
When a session file is converted to a new major version, a backup of the session-file is created. There is a popup dialog informing you about this as well.
This allows you to load the session in v6 in case you run into a critical issue. So yes, it is safe.
