300 million users and transition to WebKit

Simultaneously with the announcement of the new achievement - 300 million Opera users! - We also announce that all our new products will use the WebKit engine for rendering and V8 for processing JavaScript. They will be based on the open source Chromium browser and its components. Of course, the browser is much more than just the engine, so all these changes for ordinary users will happen somewhere far under the hood. Such users will notice only improved compatibility with sites, especially mobile, most of which have been properly tested only in WebKit browsers. The first new product will be a browser for smartphones, which we will show at the World Mobile Congress (MWC) in Barcelona at the end of February. Opera for the desktop and other products will make the transition later.

If you are too lazy to read further

• This does not require changes in your usual development process.
• Extensions developed for previous versions of Opera will continue to work.
• Opera will be involved in the development of Webkit and Chromium projects.
• We will continue to work on the development of standards for the benefit of the web.

What does this mean for web developers?

In short, it should not somehow affect your daily work. Continue to write code by standards, not for individual engines; Test in different browsers: Opera, Firefox, Chrome, Safari and Internet Explorer; use all the necessary browser prefixes along with unprefixed properties in your CSS and JavaScript code. However, something worth remembering:
