Currently Jitsi doesn't seem to support the xcap-diff event package
When two SIP users subscribe to each others presence and you are using
OpenXCAP if one user changes or loads a profile icon/picture the other user
should be notified that the other person has updated their picture and then
that user will go grab the new picture and display it for that user in the
buddies list. This currenlty doesn't happen so I was wondering when the
feature might be added?
