Microsoft is almost done with adding new features and bringing out new changes to the Windows 10 Redstone 4 insider builds (Version 1803). After some builds with mostly bug fixes and improvements, Microsoft will finalize the public release build of Redstone 4 that will be released as “Spring Creators update” most probably by end of March/beginning of April.

Now, probably starting next or next to next week Microsoft will start releasing Windows 10 Redstone 5 (Version 1809) builds to Skip Ahead ring for internal testing. Those in the Fast ring will keep receiving the Redstone 4 builds until the public “go live” of Spring Creators update.

Microsoft talked about the new preview builds on the just concluded webcast and you can check the webcast video by clicking here.

In case you have already been enrolled in the Skip Ahead ring you would be able to receive the Redstone 5 preview build automatically. It seems Microsoft won’t open enrollment to Skip Ahead and will not accept new insiders in Skip Ahead.

Redstone 5 aka Windows 10 Version 1809 may bring back the Sets feature that Microsoft removed from Redstone 4 after a brief period of limited testing.
