Opera 21 moves from the Developer stream to the Next stream.
Most of the changes are under the hood. Opera 21 supports Aura, a hardware-accelerated rendering of the browser. This enables less-taxing user-interface animations and a sleeker, more responsive feel to the whole UI. It also gives us a solid foundation on which to make future UI changes.Read more
Web developers often need to determine where an element has been placed in the page, or more generally, where it is relative to another element. Existing APIs for doing this have significant limitations. Read more
Making CSS faster and more scalable is an area of research in the WebKit project. The DOM and CSS do not always scale very well and it is sadly still common to see missed frames during complex animations.Read more
In this tutorial we will be building a notes app (like Evernote) from scratch and deploy it to Firefox OS! See a live demo.
A persistent notes app needs a place to store all the notes for a user (so no one else can read it). For this we will use my own backend solution called Sproute. Sproute is a hosted web framework for quickly building dynamic webapps.Read more

Up until now, developing web apps on mobile has been a little tricky.
After spending the time developing your app, getting your users to install it is difficult, especially when the concept of “installing a web app” is not very well defined.
The most popular method is synonymous with adding a shortcut to the homescreen. This is problematic on a number of fronts, not least because the management of web apps – especially around launching, switching between and uninstalling web apps – differs significantly from that of native apps.Read more
We are rolling out another update for the stable channel of the Opera browser. Inside you can find updated Chromium to version 33.0.1750.154. We also managed to squeeze in one crash fix, so it’s even more stable now.

The HTML5 Renderer uses WebGL, but provides fallback to the Canvas tag and functions nicely even on low-end phones. Read more
Over the next few days we’ll release a series of screencasts explaining how to start your first Open Web App and develop for Firefox OS.
It’s been a while since I posted here, heh?
Spring is coming at an impressive pace in Europe: last year we still had snow in April, but this year we probably would be able to start the swimming season in less than three weeks.
But enough of swimming plans. Here’s something more important we’re keeping pace with – our release cycle. Today we’re updating Opera Stable stream.Read more
