Release notes:

Patch Changes

• #391 `6273c96` Thanks @threepointone! - Persist a __ps_name fallback for name-based Durable Objects during initialization. This lets alarm handlers recover this.name even when firing on a stale on-disk alarm record that was scheduled by an older workerd version that didn't yet persist name into the alarm record. See cloudflare/partykit#390.

• #393 `5335251` Thanks @threepointone! - Complete the WebSocket close handshake when a client initiates the close. Previously, both the hibernating webSocketClose handler and the non-hibernating close-event listener forwarded to user onClose but never sent a reciprocal Close frame, leaving clients stuck in CLOSING until they timed out and reported 1006 (abnormal closure). The framework now reciprocates the peer's Close frame in a finally block on both paths — required by the Hibernation API on every compat date, and required by the standard accept() API on compat dates before 2026-04-07 (where the runtime's web_socket_auto_reply_to_close flag isn't yet active). Calling close() on an already-closed socket is a silent no-op, so user code that already calls connection.close(...) from onClose is unaffected. Reserved close codes (1005, 1006, 1015) are normalized to 1000 before reciprocation so they don't throw InvalidAccessError. See cloudflare/partykit#389.
