Yesterday, Gabe Aul revealed that a new Windows 10 Mobile build — in the 105xx range — would be available shortly for Windows Insiders. The release will be a major increment from the 10166 build that was rolled out over a month ago. Ahead of its imminent release, screenshots from the alleged 10512 build have leaked on China's Tieba message boards.

The screenshots don't show anything new, but the build itself is expected to bring in numerous stability improvements along with a more polished user experience. The upcoming build will be from the newer TH2 (Threshold 2) development branch, which will bring the mobile OS to parity with the desktop version before its eventual RTM next month.
