Microsoft is pushing forwards at top speed for Windows 10 Mobile now, with a major new build for the Insiders community. See below for the official release comments. The focus in build 10512 (over the previous 10166, a month ago) is in the new core models and a long list of critical bug fixes. And yes, this build really is worthy of use day to day, in my opinion.

Potentially confusingly arriving as Windows v10.0.12648.133, what's rolling out to Windows Insiders today is 'Build 10149', bringing its own swathe of improvements across the board.

Following misunderstandings and mistranslations on other sites, we have confirmed details of what will be in the upcoming Lumia Cyan update in the camera department - so at least let's put the record straight.
One of the more interesting aspects of the Build 2014 conference for developers was the principle of the unified Windows application. Can this really be a write-once run-everywhere (everywhere that is Microsoft)?
