The new version comes with two brand new (high resolution) icon packs, a new theme, and just a few minor bugfixes.
The icon pack will be changed to the new “default_mono_2014” pack if you are using the current default icon pack. If you prefer to use the classic default icon pack instead, you can switch it back and it will not be automatically converted again. Users with existing third-party icon packs will not be automatically changed to the new icon pack. The second new icon pack is called “default_colored_20142”.
The new “Modern” theme will not be set as default automatically. You can enable it or make other individual changes further more in the “Settings” under “Options” > “Design”.
