Surely it can't be changing THAT much, just some adjustments to field sizes and such?

My understanding was the changes were going to be much more sweeping than that. I seem to remember they were going to move to variable-length records so that more running order entries could fit in the limited space in an attempt to avoid the pgrzelak problem (running order too large to be preserved across power cycles.)

But for 2.0, the code I have (with some minor tweaks) would be able to spit out the FIDs in a running order or bookmark. Merging that with something that can create the playlists, etc. would be someone else's kettle of fish.
