Node Slack Sdk: @slack/socket-mode@3.0.1 Release

Patch Changes

• 5c2362c: Fix leaked TCP sockets on disconnect (#2709). Moving from ws to undici's WebSocket in 3.0.0 dropped every force-close mechanism, so ESTABLISHED sockets were never torn down and accumulated toward Slack's per-app connection cap.

  • disconnect() now arms a 30s close-handshake timeout, so a peer that never replies to the close frame no longer leaves the socket stuck in CLOSING indefinitely.
  • On the default dispatcher path, the underlying TCP socket is now captured and force-destroyed during cleanup. A user-supplied dispatcher owns its own socket and instead relies on the close-handshake timeout — this limitation is documented on the dispatcher option.
  • The close handler no longer schedules a reconnect on stale or overlapping close events, so at most one reconnect is scheduled per disconnect.
