What
Streaming responses through the local gateway now emit a periodic event: ping frame when the upstream has gone quiet, so idle proxies and load balancers are less likely to drop a long request. The interval defaults to 15000 ms.
Details
The frame carries the payload line data: {"type": "ping"}.
No such frame existed in the previous build.
Evidence
data: {"type": "ping"}
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
