PR 58476 applies…

Second theme: cleaning up Active Record's attribute method machinery. PR 58469, from Hartley McGuire, strips out "missing" workarounds that existed only to support the old six-one Marshal format—now that format is gone, so is the workaround, and it improves performance for virtual attributes as a side effect. That…

Third, PR 57973 adds native support for the HTTP QUERY method from RFC 10008 — routing, request predicates, CSRF exemptions, and test helpers all wired through Action Pack. It's a big surface change, but backward compatible: QUERY requests previously just failed with a four-oh-five, so existing apps see no behavior…
