Microsoft has announced the release of a new 19041.421 build to the Beta Channel of the Windows Insiders program that brings all the features that were detailed earlier in the Dev Channel Build 20161. This means that the upcoming 20H2 feature update will not be just a minor build as was earlier thought but will have several new UI and under-the-hood changes.
