AppKit Release Notes

Apple always seems to move the AppKit Release Notes so links regularly break, and it's not always easy to find old versions. Here's URLs that work as of 2020.8.7:

• 10.16/11.0
• 10.15 doesn't seem to have any AppKit release notes
  • there's macOS Catalina 10.15 Release Notes, but unlike 10.14 or 10.16, it doesn't link to an associated "AppKit Release Notes" document
  • the best documentation I've found is this page of raw diffs
• 10.14
• 10.13
• 10.12 and earlier
  • 10.12
  • 10.11
  • 10.10
  • etc.
