v2.0.0-next.40

Patch Changes

• 9cf2230: Route params are decoded (#670). useParams(), props.params and Router.match() return each dynamic segment decoded after matching, so /item/%E7%8C%AB gives id: "猫" and paths.item("猫") round-trips. matchFilters see the decoded value, so { k: ["猫"] } now matches. An encoded slash stays inside its param (/a%2Fb/view gives name: "a/b" for /:name/view), splat params are decoded segment by segment, and a malformed escape is left raw. match.path and location.pathname keep the URL's encoding.

  Breaking: code that already calls decodeURIComponent on params decodes twice; drop the extra decode. Encode a param (or use paths) when interpolating it into a URL by hand.

• 3832cd5: Link claims trust the server's link state at hydration: an anchor the server marked is registered without resolving its URL, and is resolved on the first routing change. Anchors with an authored aria-current, and pages rendered without server link state, are resolved at claim as before.

• 5943f7f: serverRouteComponent with a bare GET(fn) source sends one request per link visit instead of two (#677). The router hands a preload's call to the next render with the same args, so the route mounts the result the hover or focus preload already started. The hand-off happens once, within the same 5 s window query() gives a preload. A later visit calls fresh, a failed preload makes the render retry, and concurrent preloads of the same args share one call. query() and liveQuery() sources are unchanged.

• 828b232: Add useInRouter, which returns whether the calling component is rendered under a router. The other router primitives throw outside one, so components that also render there (an error fallback above the router, a shared link component) can check first instead of wrapping useLocation() in a try/catch. Like the other primitives, it throws when called with no reactive owner, such as from an event handler.
