iOS 17.7.2 released today (19 Nov 2024, https://support.apple.com/121754) is most likely the last iOS 17 update.
On my iPhone SE 2, the iOS 18 update appeared first and iOS 17.7.2 was in the other category. After updating to iOS 17.7.2, it displays a persistent notification in settings for iOS 18.1.1.
This is similar to what happened for iOS 15 & 16
