Microsoft released the final SDK for Windows 10 (Version 2004) on May 15th, 2020.
As part of Microsoft's Windows Insider's and Windows Insider's for Business programs, participants have been receiving client builds for the first feature update of 2020 for a couple of months now. That next feature update for Windows 10 , code named 20H1, is expected to be released in the Spring of 2020.
Along with those early test builds of the operating system client, the SDK for 20H1 is also now under development.
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 SDK's play a critical role as those new updates are being developed.
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.
There is no set schedule for SDK release but Microsoft usually releases new software development kits for Windows 10 20H1 following the availability of a Windows Insider Program fast ring build in the 20H1 branch. 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 20H1 Client Build Tracker, will help you keep an eye on these releases in one place instead of tracking multiple blog posts and release notes.
