The big feature that is new in this release is the new screen lock implementation. It sports a ‘shield’, which can be lifted by hitting Escape, or by dragging it up, to reveal the unlock dialog.
We had a BoF session on the new screen lock at GUADEC, and identified a number of issues that still have to be addressed.
In the System Settings, several panels have been improved.
The network panel sports a new design for the wireless page.
Connection details are available for active and saved connections, and it is possible to forget saved connections.
