[UPDATE April 7: Apple has also made the OS X 10.11.5 beta available to public beta users, as well.]
Just moments after releasing the first betas of iOS 9.3.2 and watchOS 2.2.1, Apple this afternoon has pushed fresh developer betas of tvOS and Mac OS X. The latest tvOS version released to developers today is 9.2.1, while OS X El Capitan has been bumped to 10.11.5.
The first developer beta of tvOS 9.2.1 carries the build number 13Y5742b, while OS X 10.11.5 El Capitan comes in with 15F18b.
Last month, Apple pushed OS X 10.11.4 to Mac users, while it updated tvOS to version 9.2. The tvOS update added a host of new features, including iOS-style app folders, a redesigned app switcher user interface, voice dictation input for search and username/password entry, complete iCloud Photo Library support, and much more. The OS X update added password-protected Notes, Live Photos support, and more.
The updates are expected to be relatively minor considering the major updates that were just pushed to users two weeks ago. Apple last week also released iOS 9.3.1 to the public to address more serious bugs relating to iOS 9.3. Apple also yesterday stopped signing iOS 9.2.1.
As always, though, let us know in the comments if you notice any major changes.
