What

When a streaming connection returns a non-ok response, the client now reads and discards the body with a timeout and re-checks whether the request was already cancelled before deciding what kind of failure it was, instead of tearing the stream down immediately.

Details
  • The event envelope now parses only the event type; the optional withheld payload field was removed.
  • One entry was dropped from the set of recognised notification event types.
Evidence

cli_sse_connect_http_error

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