after the last update, my old session files are not properly used; only a subset of the plugins appears.

here an example that does not work anymore:

Yes, the file format has changed.
Every data inside the Parameter tag now uses "title" writing mode, ie:
0
becomes:
0

I did this so the format is cleaner and more consistent with itself.
Also note that the way Custom-Data is saved is now different too (used in some DSSI and LV2s).

I've fixed the project file you posted, here's a fixed version:

I understand the inconvenience, so I'll update the code so it can load old projects

hi falktx,
thanks for fixing the file for me! i still think it's best to keep bwd compatibility as you plan. files could then be saved in the new format so that they are automatically converted.
