Details about new features and changes are still scarce. However, it is likely that iOS 18.2.1 is aimed at bug fixes and security enhancements. Earlier this month, Apple released iOS 18.2, which introduced new features such as Genmoji, Image Playground, and integration with ChatGPT.
Typically, Apple conducts internal testing of updates before release, and the first signs of iOS 18.2.1 have appeared in analytical reports. This indicates that testing is in full swing, according to the publication.
Meanwhile, iOS 18.3 is also in development. It became available to developers and public beta testers last week and is expected to be released in January with more significant updates.
