Not sure that all or even many .x updates were really "worthy". It seems that when there's something more than just some bug and security fixes and some things are actually changed/added/removed then it's more or less fair game when it comes to it being a .x release vs .x.y release. As far as how good those changed/added/removed things are or how visible or how useful, that's a somewhat different question.
So, not counting Apple Pay Cash, I believe in this case the following is there :
Unlock animation sped up.
New pop in animation when opening the camera from the lock screen / cover sheet.
New bounce animation on opening an app from a notification when inside an app.
Different and smoother animation when tapping the status bar to scroll to top.
Multiple emojis (up to three instead of just one) are now suggested for keywords, for example: "LOL".
AssistiveTouch now opens near where the indicator is.
Updated AssistiveTouch menu with new custom actions.
Updated icons in AssistiveTouch, for example: Siri, Home & Gestures.
Updated Camera icon under Restrictions.
Updated tab bar icons in iBooks.
Lag when using Portrait Mode is resolved
Music "Now playing" splash screen opens in the middle instead of the bottom to actually show where it is.
New Unicode 10 emoji characters
Reachability works for Notification Center
Emergency SOS Preferences tweaked
3D Touch Multitasking returns
Haptic Feedback occurs on incorrect passcode entry
Blurred Springboard is shown in empty reachability space
Messages now has a new splash screen for Apple Pay Cash setup on first opening the app
