Microsoft has released a fresh new Preview Build to Windows 10 Redstone 5 Insiders. While you can head over here to get into the details of what’s new or exciting or boring or broken, here is the news: development of Windows 10 Redstone 5 is apparently hitting the finish line!

Microsoft announced today that its focus will be now on stabilization of RS5 and that it has “forked” RS5 into its own branch called RS5_RELEASE. This means that the Skip Ahead Insiders should soon be able to start testing features slated for the release with the Windows 10 2019 edition. Excited? Not so soon…
