It's all rolling release, but Homebrew maintainers have to bump the version, not the software author (unless they put in a PR to Homebrew core or publish their own Tap). What does Arch do here?
That’s not quite true. A recipe can specify a URL to check for a new version, and the homebrew automation will periodically check it. If there’s a new version, it automates the version bump.
I used that for a package my company publishes, and neither we nor any other human AFAIK ever manually update it in homebrew, yet the newest version is always installable there.
