Earlier today, Microsoft released yet another build of Windows 10 Mobile for Insiders on the Fast Ring. Build 10581 is now ready for you to try out.
The good news? Well, there is plenty to go around. For one, for the first time since the last two builds you do not need to rollback to Windows Phone 8.1 first, which gets rid of a pain point. Additionally, performance is outstanding with this build, building on top of the excellent gains earned in build 10572. Indeed, there are some smoother animations like the fade in effect when the lockscreen clears that make using this release more enjoyable.
