Good news, Microsoft decided to start issuing release notes for its Windows 10 updates. It created a dedicated Windows 10 update history page where you can track the changes the software giant made in the latest Windows 10 builds. We certaintly apploud this decision.
We're committed to our customers and strive to incorporate their feedback, both in how we deliver Windows as a service and the info we provide about Windows 10. In response to this feedback, we’re providing more details about the Windows 10 updates we deliver through Windows Update. You'll see a summary of important product developments included in each update, with links to more details. This page will be regularly refreshed, as new updates are released.
We're currently delivering updates to two distinct Windows 10 branches. The July initial launch branch (build 10240), and the November update branch (build 10586). We introduced new operating system features in November after having previewed, or "flighted", them with our Windows Insiders between July and November. Most customers have already been moved automatically from the July branch to the November branch. Windows 10 Professional, Enterprise, and Education edition customers can defer the update to the November branch and stay on the July feature set longer — as long as 10 years for some Enterprise customers. For more info, see Windows 10 servicing options.
Here's the changelog of the latest build, which was released yesterday:
