Microsoft has just announced the release of Windows 10 SDK Preview build 18309, which developers can now use in conjunction with the Windows 10 Insider build 18309. The latter was released just a week ago and was a pretty minor update for Fast Ring Insiders.
As usual, this new SDK brings the usual bug fixes and API changes, though the release notes still include the same Tools updates mentioned for previous releases. You can get more details about all the API changes in this SDK on the full blog post.
Windows developers can download this new SDK preview build from the developer section of Microsoft’s Windows Insider website. We'll see if Microsoft will release a new Windows 10 19H1 build this week, but we’re pretty hopeful after seeing the build 18313 show up on BuildFeed today. This build is the first to come with the “19H1_release” tag, which suggests that the next major Windows 10 update has just reached a new internal milestone.
