Last we reported about a new Windows 10 Mobile Anniversary update Build 14393.33 appearing on BuildFeed. Now a newer build has shown up on BuildFeed. Windows 10 Mobile / PC Build 14393.50 has been compiled on July 29 as per the BuildFeed data and may be the likely Anniversary update candidate for release.
As expected this build may not bring any new features or major changes but may pack many fixes and improvements. Microsoft is planning to release Anniversary update starting August 2 and it will be interesting to see which 14393.xx build makes the cut.
