Hi,
I've just uploaded PyTone 2.2.1 to the usual place:
http://www.luga.de/pytone/download/PyTone-2.2.1.tar.gz
The regression with the metadata parsing code should be fixed. The debugging output has been improved and services are now restarted when they crash (let's hope they don't...). A bug in the database caching layer has been fixed.
Enjoy,
Jörg
