Sorry. Totally unusable for me. I updated it to 66 and after update, all my pages looks awful. For example: https://imgur.com/lQ7AvoL
But it's something worse. Who the hell deleted option to disable automatical update?! I was forced to restore version 65. After this restoration (and repair) some of the pages won't load (Facebook for example, but also this: https://www.apmmusic.com/albums/BR-0089). Opera loads it endlessly, and the only option is to turn off Opera and then start it again. But this helped only for one time. I had more times to turn off Opera and start it again. Luckily for me, next day was all correct. Magic!
And I thought my problems were over. I prevent Opera to autoupdate by setiing environment variable. But on Saturday's evening, after I started Opera I saw identical page look like after update to 66! After I checked it, I saw, Opera updated to 66!!! And now I have problems with this endlessly load on some pages. Facebook works ok, but APMMUSIC not., I ask you: who the hell is responsible for this <CENS> autoupdate option?! And what I have to do now, to restore correct setting my Opera WITHOUT completely wipe it out from my Computer and reinstall?!
