Microsoft has just announced a new Windows 10 Mobile Redstone build for devices that shipped with Windows 10 in the first place, such as the Lumia 950, 950 XL, and 650.



Just like before, this build is only available for the fast ring, with Microsoft saying that all Windows Phone handsets should get access to Redstone builds once they receive the upgrade to Windows 10 Mobile (which, according to new reports, should happen sometime this month).
“If you are a Windows Insider on a device not mentioned above, you can stay in the Fast ring and sit tight until we expand to other devices or go back to Build 10586 and switch to the Release Preview ring to continue helping us test Cumulative Updates,” Gabe Aul, head of the Windows Insider program, says.
New features in build 14283 The Phone app has received several important improvements in this build, including missed call and voicemail waiting indicators in tabs within the app. Just like any notification, once you click the tab, the indicator goes away.
“We’ve got another change coming that will keep the indicator in place until you navigate away from the tab. There is also a bug where you might not see the indicator clear right away - a fix is coming soon for this as well. Let us know what you think!” Aul adds.
Furthermore, Outlook Mail & Calendar has also got an improvement that we already detailed in an article yesterday. Starting with this version, you can turn off the message preview text in the message list and get rid of junk email in you inbox with a new “Move to Junk” option.
Aul has also announced that future builds will merge the Insider Hub and the Feedback app into a single tool called Feedback Hub. The new app will include all features and will let you upvote feedback, see new announcements, complete achievements, and quests.
Just like the previous builds, this new one is available via the phone update tool, but remember that it’s only available on devices that launched with Windows 10 Mobile.
