IPadOS 15

iPadOS 15 is a major update to iPadOS that was developed to succeed iPadOS 14. It was announced on June 7 at the 2021 Worldwide Developers Conference and was released on September 20, 2021.

New features
Newly announced features include:
 * SharePlay feature allows shared viewing of video or listening to music with friends during FaceTime calls.
 * Focus settings allow users to block distractions while working or doing other activities.
 * New summary feature for Notifications.
 * Live Text automatically recognizes written or printed text in images or photos that can be converted into selectable text.

Earlier development
In Spring 2021, Apple began beta testing its new anti-tracking privacy feature to shield user information from websites. However, this feature was already deployed with the release of iPadOS 14.5 on April 26, 2021. Facebook reportedly planned to file a lawsuit against Apple's tracking feature changes as "unfair".

Supported devices
Contrary to early reports, iPadOS 15 will support all previous models that could support iPadOS 13 or 14. Features that require newer hardware, such as spatial audio will be disabled in older models.
 * iPad (5th, 6th, 7th, 8th, 9th generation)
