  • We've added a public, read-only ts property to ChatStream and AsyncChatStream, enabling users to call the chat.update API method as a fallback when the server closes a stream due to undocumented timeouts.
  • We made the thread_ts argument of the assistant.threads.setSuggestedPrompts API method optional.

The text above is Slack's. reef added the severity, the dates it could read from the text, and the endpoints and scopes named in code.
