Microsoft has released today a new cumulative update with no changes for Windows Insiders in the Dev Channel. The build 21390.1000 (KB5004071) is just another servicing pipeline test, and the Windows Insider team explained today that more will come in the coming weeks before we go back to regular build flights.
"We have been testing our servicing pipeline with Cumulative Updates to the builds released to the Dev Channel. Each week, we would release a new build and then follow up with a Cumulative Update on top of that build before moving to the next build. However, we need to test the process of releasing multiple Cumulative Updates on top of each other on top of the same build. As a result of this, over the course of the next several weeks, our focus will be on releasing multiple Cumulative Updates on top of Build 21390. Having Insiders in the Dev Channel test this will be immensely helpful, and we’ll be back to flighting normally again soon," the Windows Insider team explained today.
With Microsoft expected to unveil the next generation of Windows on June 24, it's no surprise that Windows Insiders aren't going to see major new features before that event. The software giant likely doesn't want to spoil the "Sun Valley" reveal, even though traces of the design changes have already been spotted in recent Insider builds.
