Apple has been testing iOS 15.3 and iPadOS 15.3 for a few weeks now and the publication of the release candidate already made it clear that it won’t be long before the final version is rolling. That just happened, so you can now go to settings and download the new update.
If you are hoping for major changes now, I have to disappoint you. Apple uses this software release to fix bugs and improve stability and performance. Among other things, this release fixes the bug within Safari that allowed malicious websites to track your surfing history.
So you shouldn’t wait too long with the update. Also in the luggage: updates for watchOS, the HomePod and the Apple TV.
Changelog:
iOS 15.3 includes bug fixes and security updates for your iPhone and is recommended for all users.
