As a literal footnote to the "California Streaming" event, Apple has announced that iOS 15, iPadOS 15, watchOS 7, tvOS 15 will be available to the public on Monday, September 20.
The operating systems were originally announced at the 2021 WWDC, and have been in beta testing ever since.
For iOS 15, Apple introduces Focus modes, Live Text OCR, a digital ID for Wallet, enhancements to Messages and FaceTime, and updates to Weather and Maps, among other changes.
iPadOS 15 gains improvements to multitasking, as well as home screen widget support, a system-wide Quick Note feature, and the addition of the Translate app. For developers, Swift Playgrounds will allow app development on the iPad, including App Store submissions.
On watchOS 8, users can expect the addition of Tai Chi and Pilates workouts, respiratory rates in the Sleep app, new Photos layouts and memories, and Digital Crown cursor control and GIF search for Messages.
The new versions of iOS, iPadOS, and watchOS are required for the iPhone 13, and the rest of the devices announced during the "California Streaming" Apple event.
