iOS 14 and iPadOS 14 are no longer getting any new security patches as Apple has reportedly confirmed that giving updates on the older software versions was of “temporary” nature. The move would help the company expand the base of iOS 15 and iPadOS 15.
After releasing the iOS 15.2 last December, Apple just recently launched the iOS 15.2.1 update to patch bugs and security problems experienced by iPhone and iPad users. Furthermore, iOS 15.3 will be released in Spring.
iOS 15.2.1 and iPadOS 15.2.1 have been released by Apple for all compatible iPhone and iPad models as a minor update that fixes a known denial-of-service vulnerability existing in HomeKit.
