Do you still have an iPhone 6s or an iPad mini 4? Then you can also update those devices now. Apple has released iOS 15.7.4 with important bug fixes. And there are also updates for the Mac. 
Once in a while, Apple releases a new iOS and iPadOS update for people with a somewhat older model. These are models that can no longer be updated to the latest version (currently iOS 16 and iPadOS 16), but are still in use by a relatively large number of people. Consider, for example, the iPhone 7 and iPhone 6s series, which have not been able to be updated to the latest major update since last September. Especially for those people, there is now iOS 15.7.4 and iPadOS 15.7.4.
