Some fonts are redownloaded/reinstalled with every `brew upgrade` even when no changes are in those fonts about homebrew-cask-fonts HOT 2 CLOSED

Here's the log from reinstalling all those fonts (notice all of them have Warning: No checksum defined for cask 'font-caskname', skipping verification.):
`$ brew install font-tuffy font-titillium-web font-roboto font-rem font-open-sans font-life-savers font-lekton font-fruktur font-changa-one font-cabin-condensed font-cabin

@duanemoody This is because the fonts have no version information available. The version is :latest - using brew upgrade --greedy will upgrade these fonts every time as we have no way of knowing if they have been updated or not.

You could try using brew upgrade --greedy-auto-updates instead which will upgrade casks with auto_updates true set but not those with version :latest.
