TechCrunch: (January 27th 2015):
“The former CEO of Opera, Jon von Tetzchner, has released the Vivaldi Browser for fans of the old Opera. This initial release is a Technical Preview, i.e. it is neither feature complete, nor free from bugs that might spoil your day. It uses the Chromium rendering engine like the new Opera 38. It already has Panels, Tab-stacking, Notes, Speed Dial, and Customisable shortcuts and Tabs. Built-in email is planned, but mail is limited to web mail at the moment.”
