Yesterday came the next update 
Opera 12 (Wahoo). The list of corrections and changes is quite large, but basically they all relate to the technology 
Do Not Track , "opera" mail and the theme. The Norwegians did their best and the last Changelog was pleasantly surprised.
Released assembly consists of many fixes, improvements and changes.
Still, one of the most interesting features, in my opinion, added by 
Opera 12 is the support of the technology 
Do Not Track , which allows users browsers to prohibit their tracking on the Internet. (a little more about this can be read on the link at the end of the topic)

A number of works with SSL performance was also done, for example, such as:
- Parallelization of OCSP / CRL uses half the time to check for undo operation
 - Improved session negotiation to save latency
 
And a few others.
In fact, the list of fixes and changes is much larger. To see it fully, I suggest reading the full translation (of my 
buddah colleague) of this news in 
this article.
