Back in early January, Microsoft did a thing which they only usually do when preparing for a big public Windows release, and that's jump development builds. January saw the company jump from build 99xx to 10000, giving the development team breathing room to continue compiling candidate builds in the 99xx range for the January Technical Preview.
The same has happened again today, with the company jumping from 1006x to 10100. To Insiders, this doesn't mean much. But If history is to repeat itself, todays build jump is allowing the development team a bit of breathing room to continue compiling candidate builds for the BUILD Insider Preview, which could end up being compiled around 1007x or 1008x.
It's good to see Microsoft getting into gear for BUILD, as the conference is but a couple of weeks away now. Microsoft is expected to unveil a 'feature-complete' build of Windows 10 at its annual BUILD conference, along with more Windows 10 mobile changes and more HoloLens action.
