Opera Software, the company behind the proprietary Opera browser, announced that it will stop developing its own Presto rendering engine in favour of a switch to a WebKit-based solution over the course of this year. The announcement comes as the company celebrates 300 million monthly users of its browser products on the desktop, mobile devices and TVs.

Opera CTO Håkon Wium Lie summarised the reason for the decision by saying: "it makes more sense to have our experts working with the open source communities to further improve WebKit and Chromium, rather than developing our own rendering engine further."
