[Chandler-dev] IMPORTANT: Upcoming Chandler update will break compatibility

[Davor Cubranic]

What about shares on cosmo-demo? Do they need to be migrated? Or are they 
safe as they are?

How difficult would it be to extend Chandler to include some custom 
headers into the ics file that would allow us to preserve all data? It 
could be temporarily added to the code and not part of the normal "export 
to ICS" menu action (maybe in Test?).

And what about the old shares? Will they eventually be removed and by 
whom? I don't mind cleaning mine up myself, just let us know if we should 
worry about it or if there will be a mass purge of old shares at some 
point.
