Is there anywhere to find iOS API diffs any more?

Up through iOS 16 it looks like there were a couple of web sites that had some documentation about iOS API changes (e.g. http://codeworkshop.net/objc-diff/sdkdiffs/) and for IOS 11 and earlier Apple had official pages. I'm trying to figure out if there have been any public API changes between iOS 18.4 and 18.5, and Apple's release notes have not been very good for this. I prefer first party documentation, but in absence of that any documentation to review would be welcome. Is anything like that available for recent releases?
