   **Server:**
+
   - Replace in-memory `WSSharedDoc.conns` Map with `connection.setState()` and `getConnections()` so connection tracking survives Durable Object hibernation
   - Move event handler registration from `WSSharedDoc` constructor into `onStart()` to use `getConnections()` for broadcasting
   - Disable awareness protocol's built-in `_checkInterval` in `WSSharedDoc` constructor to prevent timers from defeating hibernation

   - Widen `onLoad()` return type to `Promise<YDoc | void>` to allow seeding the document from a returned YDoc
 
   **Provider:**
+
   - Switch awareness event listener from `"update"` to `"change"` so clock-only heartbeat renewals do not produce network traffic (allows DO hibernation during idle sessions)
   - Disable awareness protocol's built-in `_checkInterval` on the client to stop 15-second clock renewals and 30-second peer timeout removal
   - Remove provider's own `_checkInterval` liveness timer (was coupled to the awareness heartbeat)

+
   - getServerByName was throwing on all requests
   - `Env` is now an optional arg when defining `Server`
   - `y-partyserver/provider` can now take an optional `prefix` arg to use a custom url to connect
   - `routePartyKitRequest`/`getServerByName` now accepts `jurisdiction`
 
   bonus:
+
   - added a bunch of fixtures
   - added stubs for docs
