Good and necessary fixes were included in this version. Well done. Although there's one (major) bug that hasn't been fixed since a long time: the reload function. It still jumps randomly backwards, messing with the current position of the page.
I have to edit/update content frecuently on documents and web pages, so I use the reload very often to check the changes, but Opera is a pain in the *** to do that because it never stays in the same place. Because of that, I had to switch to Firefox to do that work properly and it does a solid work with that, unlike Opera. The reload function used to work fine until Opera 64. I don't know about Opera 65-66, but this issue has been present since Opera 67...
Besides that, I see another (minor) issue that has't been considered: the transparent line drawn under the Opera menu button. It's very fine, like 1px in height but it's still annoying to see it all the time.
Cheers for the team. Hopefully you can fix the reload problem soon. In the meantime, I'm forced to go back to Firefox.
