Microsoft has released Windows 10 Mobile Insider build 15051 to the Fast Ring, offering up a very small set of changes for Windows 10 Mobile. This time around, we've only got some bug fixes and tweaks - no new features were introduced with 15051.

Along with the build, we also got a small community update regarding Paula Aliu, the CEO of Cogno-Aid in Nigeria, who is a Windows Insider working to help fight the stigma against mental health care. It's an excellent read, especially if you feel like celebrating the Insider program a little.
The build is available for download right now - Enjoy, and remember to report any bugs as you find them!
