Update: Apple has also today released the first OS X 10.11.2 El Capitan beta build to public beta testers. This build follows the public launch of OS X 10.11.1 last week. You can sign up to join the public beta program on Apple’s beta testing website
Following this week’s release to developers, Apple has seeded the first version of iOS 9.2 to public beta testers. The update brings some important changes to the Safari View Controller, which serves as the in-app browser for many apps in iOS 9.
Those changes include the ability to reload a page without content blockers and the option to use any type of Safari extension (previously certain kinds of extensions would not be offered in the share sheet).
Public beta users can download the software from the Software Update section of the Settings application.
