Interestingly, this update showed no icon and no changelog and at first, I thought this update might have been released accidentally.

But it seems to be a security update, according to Apple it’s related to HomeKit (Apple’s Smart Home framework):

Available for: iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch (7th generation)

Impact: Processing a maliciously crafted HomeKit accessory name may cause a denial of service

Description: A resource exhaustion issue was addressed with improved input validation.
