<![CDATA[New Opera developer 44]]>The first Opera developer 44.0.2440.0 (for Windows only). The announcement 😉

"We are working with making Opera even faster on Windows machines, using a technique named “PGO” (Profile Guided Optimizations”), and it’s time to show off the first results.

This is preview build for public testing. Note, that auto update is disabled. If you like to check this build, just grab the installer.

What is PGO?

Most of Opera is written in C++, and it is the C++ compiler’s job to convert the C++ to machine code, that a computer can run. Unfortunately, it cannot try to make all the code fast, because that would make the program huge (and slow), so instead it tries to find a balance where programs become reasonably fast.

With the help of Profile Guided Optimizations (PGO) we can do better. By selecting a number of important scenarios, the training set, we can teach the compiler, what code is important, and what is less important. There is for instance code to handle errors, and rarely used web features, which does not have to be extremely fast, and can instead be made small and efficient. The same for code related to user interaction. It does not matter to a human, if a click is processed in 2 milliseconds or 1 millisecond, since humans are slow.

Test environment

The results below are from a computer running Windows 7 x64, using an i7-6700 CPU locked at 3.4 GHz. In the startup tests Opera was stored on an SSD. We’ve compared x64 build number 43.0.2440.0 compiled with, and without PGO.

Results

We see improvements on a lot of different tasks, so we think we have trained the compiler well. It now seems to do a good job, optimizing the most important parts of the browser. Below, are some numbers we have collected, but note, that this is still work in progress and this is just a snapshot data.

Startup time

We see a 13% faster startup in our testing, using the computer described above (SSD, and enough RAM to avoid paging).

Web page library speed

The Speedometer benchmark is 5% faster with PGO.

JavaScript performance

Since JavaScript is not compiled by the C++ compiler, we would not expect much change. However, tests show that:

– The Sunspider benchmark is 2.4% faster with PGO.

– The Octane benchmark is 1% faster with PGO.

Future

We are still tuning the builds to get the largest impact. We want to have the largest improvements where it matters the most, and I don’t think we’ve reached the optimal training set yet."

The Chromium has been updated to version 56.0.2924.10.

Of course Opera still shows you a badge with the site domain name for security. But why is there all that empty space above the security badge?

How about implement the Neon style speed dial? I mean the background showing the desktop wallpaper and the circular icons... That was a nice touch... 🙂

Example:

Because this is not useful. I think better to replace this sidebar with Panel of Opera Neon. And If Opera Software will keep to develop this sidebar, I think better to show popup the speed-dial and bookmark and history like Messenger and that of Opera Neon than moving to speed-dial page and bookmark page.

It works fine on version 43 stable, so probably it's just a bug...

But 43 doesn't have Reborn features, therefore it does not have a dark skin.

I thought he's talking about the "Show system color on top bar", which I think is an theme-independent feature (I guess?)...

Might only apply to the old XP-style Windows themes anyway (in XP, Opera tended to always use blue on the top bar, even if your theme was olive - as mine was). As 44 will never run on XP and is no longer transparent in 7 with the standard theme, probably no longer functional. In Windows ... I guess I'll need to check on Linux.

(just open the window and then in the task bar click opera.)

(minimizing the window this "fixes", yet you need some type of program that has a black backroung if you don't want these lines)

But there's a minor issue with the new sidebar... If you use the extensions sidebar like I do, you will end up with two sidebars, see:

Alt text

which is not great, it's a waste of space.

Would not be better to merge this two sidebars into one? The facebook messenger already looks like a sidebar extension, so it would be nice.

Other thing, the extensions sidebar color should match the new one, imo.. Besides, when you switch to the dark theme, the extension sidebar remains the same light color... needs fix..

And yes, add Telegram to the sidebar, please asap... 🙂

Crashing when moving tabs out of the window and putting back. See:

The change log, and the announcement.

"Today, we’re bringing you a brand new refresh of our user interface in the developer stream. This work is part of a bigger project, code-named Reborn, which we will tell you more about soon. However, starting from today, you can preview its fresh look, and the new set of features.

Brand new look and feelOpera's entire design has been updated with a new, high-quality graphical design that is less platform-specific. The tabs are simplified, lighter and more elegant, making it easier to locate open tabs. The new sidebar is more subtle and refined, with a touch of animation. Speed Dial has also been given a fresh look with smooth animations.

Two colors

Opera is now available in two theme colors: light and dark. We’ve also designed three new backgrounds, that perfectly complement Opera’s new look and feel. Both, the background wallpaper, and the browser color can be managed under Themes.

Browser sidebar

Opera’s sidebar has been moved from Speed Dial to the main browser window, similar to how it is in Opera Neon. This first version of the new sidebar gives you one-click access to important tools, such as bookmarks, history, personal news and extensions. You can customize the tools, that appear in the sidebar, according to what you find useful.

The new sidebar will be visible by default for new users (current users will have the option to turn it on by flipping the switch in Speed Dial).

Sidebar for Facebook Messenger

Communication is truly important on the web, but today switching between tabs, when responding to a message is cumbersome, and inefficient. In this version, we have added the ability to keep Messenger.com – Facebook Messenger’s standalone website – as a side tab. More social services are planned in the future.

To use Facebook Messenger in Opera, click the icon on the top of the sidebar. After you log in to the site, there are two ways of using Facebook Messenger in the sidebar: you can open it in overlay, or pin it, and use it side-by-side with your current tab. The second option allows you to combine online chat with a full browsing experience.

Zero-click network installer (for Windows)

We’ve been working on providing you with an even quicker, simpler installation process. If you install Opera Developer for Windows using this link, the installer will start the installation process right after it’s launched, requiring no further clicks. The same solution will soon be available for everyone who downloads Opera at opera.com.

Of course, you can still go through the full installation process by choosing the “Download the offline package” option on our download page, or by using a USB installer.

Chromium is updated to version 57.0.2987.19.

Same problem as described on the blog. I use Opera Developer to develop and try out extensions. No more I guess, forced to be on hold.

Known issue, I don't like the attitude shipping products in this state, it's disrespectful to other software, forcing a user to remove Chromium. Better skip a version, if you can't make it work.

Hopefully it will be fixed soon.

Regarding the H264 issue, you can try a temporary workaround as follows (it works in my case):

  1. Download the opera-developer-ffmpeg-codecs-56.0.2924.10-1 package from the Heracura's repo: 32-bit, or 64-bit version,

  2. Navigate to the Opera's root folder, create a new subfolder "lib_extra", and extract the "libffmpeg.so" file from the package to this subfolder.

Opera Developer 43: Extension - Background worker

Is there a way to disable (Background worker) extension?

Hi @rocky-iv, you can try to follow the below steps (it works in my case):

  1. Open a terminal window, and run the Opera with the command line switch as follows:

/usr/bin/opera-developer --show-component-extension-options

  1. Open the "Extensions" page (Ctrl+Shift+E), scroll down to "Background worker", and click the "Disable" button.

After that you can launch the Opera as usual (without the above switch).

Maybe you need to enable it on opera://flags. You should also not that some of those features may not be available yet.
