I don't know what their official policy is on breaking changes, but packages published via Typst Universe[1] are versioned, and you specify the exact version you want when importing a package in your document. So while you may need to install an older compiler (which is a single, self-contained executable), I don't think that you'll have to worry about your dependencies [1] https://typst.app/universe/ https://typst.app/universe/
