Microsoft ended development of the Redstone 5 Software Development Kit for Windows 10 Version 1809 on 02 October 2018 and the final build was 17763
If you are a Windows Insider then you know Microsoft regularly releases testing builds for their upcoming feature updates of Windows 10 during its development cycle. Currently the company is releasing builds for its sixth feature update under the code name Redstone 5 (RS5).
For developers a feature update to Windows 10 means new capabilities and features that can be accessed through system APIs in the updated operating system. That means time needs to be spent updating the underlying code of current enterprise, business, and consumer apps so they are ready when that next feature update is released. That is where software development kits (SDK) play a critical role as those new updates are being developed.
Microsoft knows this and so right alongside of the Windows 10 Redstone 5 (RS5) builds they release to members of the Windows Insider Program, they also make available an updated Windows 10 Redstone 5 (RS5) Software Development Kit (SDK) release. This SDK contains the new APIs for updated features and capabilities that the developer can access and put to use in their own apps as the operating system is being updated. That means once the new feature update for Windows 10 is ready, these developers can also release updated apps immediately that are ready to take advantage of those new features.
Although there is no set schedule, Microsoft typically releases new software development kits for Windows 10 Redstone 5 (RS5) following the availability of a Windows Insider Program fast ring build. That means there is usually a one week period of time between the release of a fast ring build to testers and the availability of the new SDK release for that build.
This tracker, along with our Windows 10 Redstone 5 Build Tracker will help you keep an eye on these releases in one place instead of tracking multiple blog posts and release notes.
