During the weekend, Microsoft's Joe Belfiore tweeted confirmation of something that has been suspected for many months: Microsoft is no longer developing new features or new hardware for Windows Mobile. Existing supported phones will receive bug fixes and security updates, but the platform is essentially now in maintenance mode.
Microsoft's difficulties in the mobile market are no secret, but for a time the company looked as if it was keeping Windows Mobile as a going concern regardless. Through 2016, Microsoft produced new builds for the Windows Insider program and added new features to Windows Mobile. At around the time of release of the Windows 10 Creators Update in April this year, that development largely ground to a halt. Windows Mobile, which already lacked certain features that were delivered to Windows on the PC, had its development forked. PC Windows development continued on the "Redstone 3" branch (which will culminate in the release of the Fall Creators Update later this month); Windows Mobile languished on a branch named "feature2."
