Versioning

Archive and serve older documentation versions alongside the current one, so nothing links to a page that moved.

Older documentation versions are archived and stay reachable under their own version path, instead of being deleted when the docs move forward.
A reader on an old version sees the docs that actually matched that release, not today’s rewritten instructions.
Navigation, breadcrumbs, and generated indexes are version-aware, so a versioned page still gets correct prev/next links within its own version.
No separate hosting or deployment is needed per version — archived versions live in the same deployment as the current docs.
