The contact list in GNOME's messaging and chat application Empathy received a cleaner design which makes the presentation of contacts consistent with Contacts. Groups have been disabled by default as we noticed most people do not make use of them. Instead, we make contacts easier to find using the integrated live search. If you still want to group contacts, this can be enabled in Preferences.

Top Contacts are always displayed at the top of the contact list. This contains the contacts that you have tagged as favorites but also those contacts that you talk to the most often.
