Well i am surprised its probbably a first patch which has no major bugs.
But as far as i know apple when millions of people download it they ditch much more than single person from GSM Arena.
So there is nothing to congrats on :-)
"The need for speed"
People voted for improved speed on the new iOS.
Hope that my iPhone 6 will work fine on iOS 12. In iOS 11, it's really bad big time. I experience slow downs and slight lags compared to 11.3.3. By the way, I never updated to 11.4.
