Rather burying Mozilla’s announcement (a coincidence, I’m sure), is the news on Blink:

WebKit is a lightweight yet powerful rendering engine that emerged out of KHTML in 2001. Its flexibility, performance and thoughtful design made it the obvious choice for Chromium’s rendering engine back when we started. Thanks to the hard work by all in the community, WebKit has thrived and kept pace with the web platform’s growing capabilities since then.

However, Chromium uses a different multi-process architecture than other WebKit-based browsers, and supporting multiple architectures over the years has led to increasing complexity for both the WebKit and Chromium projects. This has slowed down the collective pace of innovation – so today, we are introducing Blink, a new open source rendering engine based on WebKit.

The only surprise is that it took this long; Chrome and all its parts are the centerpiece of Google’s strategy going forward. The Cook doctrine – “We believe that we need to own and control the primary technologies behind the products we make” – is not just reserved for Apple.

And now it seems the Apple-Google divorce is complete.
