Snapshot 20151123 changed fonts for openSUSE. The terminal font changed to Adobe Code Pro and Roboto was also added as the default font.
The fonts are not only available in Tumbleweed; users of Leap can update the fonts as an option. The reason for the change was to provide a more appealing, complete font.
Wireshark upgraded to 2.0 in Tumbleweed and the new features are a new user interface. The legacy interface is expected to be removed in Wireshark 2.2. Wireshark’s RPM-based package definition provides the new interface in the “wireshark-qt” package and the old interface in the “wireshark-gtk” package.
