iOS 15.2.1 is out now, with fixes to CarPlay and Messages
Apple has released iOS 15.2.1 to the public, one month after iOS 15.2 introduced features like a redesigned summary page, Apple Music Voice plan, App Privacy Report and more. This is mainly a bug fix and improvement update, with fixes for CarPlay after users found third party apps were not responding to input. There were also some issues sending photos in messages, but these have been addressed in this update.
iPadOS 15.2.1 is also released, and can be updated from the settings app.
iOS 15.3 is still in beta testing, also with a performance focus and not being as feature rich as the previous 15.2 update.
