Only had to reinstall xcode dev files. Everything else is just fine, some things are a bit faster even. Nothing broke.
And of course, native dark theme! 
Yeah the xcode thing is a given with each update. Dark theme is awesome.
I had a big issue for rails project that require capybara webkit because of gcc but that was the only real issue I ran into.
FYI I had to ditch webkit as a headless driver and moved to a chrome’s headless web driver.
