DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

WebSocket Connection Handling

  • Permanent close detection: WebSocket connections now recognize permanent close codes and avoid unnecessary reconnection attempts
  • Bun ping support: Added specific ping handling for Bun runtime WebSocket connections
  • Sessions WebSocket: Similar permanent close handling for session WebSocket connections
Evidence

WebSocket improvements (search for "WebSocketTransport: Permanent close code" and "Sent ping (Bun)")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
