How to generate list of Homebrew formulas/packages sorted by "most recently updated" (by package provider)?
Open this folder in Finder:

/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula

⌘ ⇧ G in Finder will bring up a “Go To Folder…” dialog box. You can then paste the path from above into the box.

Then press ⌘ 2 to switch to list view and then click “Date Modified”.
