Did they switch to Blink or Webkit? I thought it was the later.
Either way, meh. Never liked it as a browser, dislike it even more now. Their installer hides the "Make Opera my default browser" (ticked by default) under advanced options and performing upgrades doesn't remember this settings. And it also makes itself the default torrent app on your computer without asking you.
If Microsoft or Mozilla tried making their browsers the default without it being plain obvious, there would be a shit storm.
And also, who in their right fucking minds wants a torrent client built into their browser?
