Firstly, thanks to Opera team for this release. Webpages are responding more faster, animations looks better and Google Docs problems with copy/paste, PDF reader and AltGr+<letter> are fixed. Web is really more enjoyable now and you make my cyberlife easier.
But there's bug. I've the same bug as +Илья Найдов
and +Sam Wong
. The Google+ Chat column doesn't work well with SPDY enabled. The bug happen only 99% times but I got it works with SPDY enabled two times. GMail has some random bugs. Sometimes it loads, sometimes it doesn't, sometimes it shows a 413 error. I disabled SPDY. But should note that website loads really fast with SPDY enabled, even without any caching (tried with GMail).
Another less annoying bug with Google+: Can't upload a picture of less than 50 KiB. I tried with Opera 11.64/12.00/12.01/12.02/12.10 and Flash 11.2/11.3/11.4, it doesn't work and Opera freezes. See this topic: http://my.opera.com/community/forums/topic.dml?id=1512082
