Thanks for the updated version.

Conspiracy theorists: They might be able to do all kinds of tracking not only through the Windows binaries, but also through the online/call-home functionality like Dragonfly and whatever home servers Opera communicates with.

Some details on the v12.18 update here:

Is there any reason to leave TLS 1.1 and 1.2 in their default, disabled, state? What about SSL3?

Thanks. How did you find out about it? I'd never think to search for it.

You can get it here:

(Silly that there's no obvious way to get there using the site navigation. Luckily a search engine finds it.)

No changelog:

Signed with Google? AFAIK Opera just decided to stop developing their own HTML/layout engine and instead switch to one developed by multiple parties. For some reason they also decided to build an entirely new browser around that.

I guess the Opera spirit lives on in Vivaldi:
