Apple has released iOS 13.3.1, iPadOS 13.3.1, watchOS 6.1.2, macOS 10.15.3 Catalina and tvOS 13.3.1 to the public, with the latest versions offering bug fixes and performance improvements to iPhones and iPads as a smaller incremental release, rather than offering major new features.
Released on Tuesday, the update replaces the previous versions of the operating systems, iOS 13.3 and iPadOS 13.3, which shipped on December 10. Users can manually update their iPhone and iPad by accessing the Settings app then selecting General, then Software Update, followed by the option to install the update if it is made available to them.
Users with automatic updates enabled will be advised of when the update has been downloaded to their device, with a notification informing it is ready to be installed. The updates weigh in at 275.1 megabytes for iOS, and 181.7 megabytes for iPadOS.
For owners of the iPhone 5s, iPhone 6, iPad Air, iPad mini 2, and iPad mini 3, an update is also available that brings their iOS installations up to version 12.4.5.
The release arrives after a total of three beta cycles that took place throughout December and January. The most recent beta attempt was on January 22 for most of the operating systems, but January 24 for macOS Catalina.
While Apple declined to offer details of changes in the release notes for the betas, the incremental number change indicated the alterations would be small in stature, and not introduce new features.
