So far, I have been comparing hashes between 11.5.1 and 11.5.2 across a limited range of directories, but here are the changes in 11.5.2 that this has already revealed[…]


I think the evidence points to Apple having made significant security fixes in 11.5.2, as well as fixing bugs across important frameworks.

I wish someone just ran a script every time a build appears that compares hashes, or at least version numbers, so we have a vague idea of which areas this build tackles. (Mr. Macintosh does list that this includes a different Safari build. What about, say, Mail?)

Just a dump of all bundles with their main binary hashes and Info.plist version numbers, then update, then run the dump again, and diff.
