Apple Seeds Fourth OS X 10.11.2 El Capitan Beta to Developers and Public Beta Testers

Apple today seeded the fourth beta of an upcoming OS X 10.11.2 El Capitan update to developers and public beta testers, just one week after seeding the third beta and a full month after releasing OS X 10.11.1, the first OS X El Capitan update, to the public.

The fourth beta, build 15C47a, is available through the Software Update mechanism in the Mac App Store and can be downloaded through the Apple Developer Center. Public beta testers can download the beta through the Mac App Store.

We don't know exactly what improvements the 10.11.2 update will bring to OS X El Capitan, because the betas seem to be focused on under-the-hood upgrades with no apparent outward-facing changes. It’s likely to include bug fixes, security enhancements, and performance improvements to address problems that have popped up since the release of OS X 10.11.1.

Apple's release notes for OS X 10.11.2 have asked developers to focus on Networking, Graphics, Mail, Wi-Fi, Calendar, USB, Notes, Photos, and Spotlight.

So now this is considered front page news again? Last week you moved it to the Mac Blog and now it's back once again. How is this even rumors?! This, while the rumor of a new 4" iPhone is moved OFF the main page to the iOS Blog.
Any OS X/iOS updates should be front page news by default imo. Macrumors is a website name. Not everything has to be a rumor.

I hope they've fixed the annoying bugs that existed since the first ever El Cap public beta. Especially the bug that makes the system unresponsive from time to time.
