[Ardour-Dev] session migration 2.x -> 3.x and current 3.x session format

[Robin Gareus]

Hello *,

How frozen is the current (r7832) ardour3 session format?

I'm asking because I'm about to start some projects for which I'd love
to use the videotimeline in ardour3.

I (probably) don't need MIDI tracks, but I require plugin-automation and
want to be able to load the session again with future versions.

Well, I know A3 is still highly experimental, but recent tests made me
confident that the features I require are working or that I can
fix/patch/work-around them, however messing around with hand-editing
session-files is no fun.


And a related question:

In a message on this list from Nov 19, 2008 Paul Davis wrote:
"3.0 will open most 2.0 files but the reverse will never be true."

Is that 'most' quantifiable? fi. known issues or edge-cases that won't
be fixed in a foreseeable time-frame.

I realize that a definitive answer is impossible, but an educated guess
would be nice.

Thanks,
robin
