Yesterday, Microsoft rolled out Windows 10 Mobile Insider Preview build 10149 - its second new build for smartphones in nine days. It's a different story for those testing Windows 10 on PCs, though - their last official build remains 10130, which Microsoft released almost a month ago.
Last week, build 10147 leaked onto the web, as did the internal release notes for that build. But today, release notes for the even newer build 10154 have been revealed by WZor.
You can check out the release notes in the gallery at the link below.
