This is an Opera 12 (Wahoo) snapshot.

As you can see from the changelog, this build introduces quite a few fixes, changes and improvements. Since there's a lot of it, I'll highlight a few important things below.

Privacy

This Wahoo builds adds support for Do Not Track, which allows browser users to opt out of being tracked on the web. It is currently disabled by default, but can be enabled by enabling the following option in Opera's Preferences dialog: "Preferences > Advanced > Security > Ask websites not to track me"

Note that this will only work if the site actually honors the request. Few sites currently do, and the effect of DNT will have to be evaluated to see if it is a viable solution in the long run.

SSL performance

This build also introduces a first round of optimizations for faster SSL handling (CORE-41667):

• TCP optimization to eliminate roundtrips
• Improved session negotiation to save on waiting times
• Improved connection handling which improves both HTTP and HTTPS connections
• Quicker closing of connections allows for new connections at an earlier stage
• Parallelizing OCSP/CRL uses half as much time to do revocation checking
• Strict transport security improves security and will also improve speed when servers start using this feature

As an example, the first load at skandiabanken.no was reduced by one second or more. With 10 subsequent page loads, the time to open the page was almost cut in half in total.

XHR

With CORE-41784 (XMLHttpRequest Level 2 upload and progress events), we completed our support for progress events in XMLHttpRequest, for upload, download, and timeout update. This will improve the upload experience on Google services (no more Flash uploaders on YouTube and Gmail), and more sites are to follow.

More

There are numerous other improvements, including Core, mail and theme fixes. Take a look at the changelog for more information.

Hello everyone!

My name is Kristine and I'm an all year round intern in Desktop QA. It’s been 938 days since my last blog post and it's good to be back

We are preparing another maintenance release for 11.6x ‘Tunny’ with some stability fixes. This is a normal Opera release, not Opera Next. All of the below fixes are already in the current Opera Next release.

Known issues

• [Mac] Address field blinks while typing
• [Linux] The 64-Bit build has a different build number but is in fact identical

We have already introduced address field search suggestions powered by our partners Google (default), Bing, Яндекс (Yandex), and Wikipedia (English only). Now we want our own address field suggestions to meet the same high quality standards as the ones provided by our partners for your bookmarks and history entries.

In our old system; everything including bookmarks was matched against page URL, title, or page content and then ordered in one giant list sorted by last visited time.

The new system assigns a score to each suggestion based on more factors than just the last visited time. For example, we prioritize your bookmarks, the position in the URL where we find a match, and the number of times we get a match on the page.

We are not done yet, and will work on integrating Speed Dials and further improve the scoring system.

What do you think about the new results in the address field? Are we getting you to where you wanted to go?

If you already know exactly where you want to go and don’t care too much about the above improvements; then you will certainly appreciate that we’ve also worked on getting you on your way faster. (Nice segue, huh?) Start-up times and session handling should be snappier in this build. We’ve ironed out a bunch of smaller issues that we think will make a big difference.

PS: There are some other treasures in the change log as well.

Known issues

• Mail header layout is broken
• Mac: File uploading, and large network requests never finishes
• Mac: Some font rendering issues and crashes with Web fonts
