- The data plane treated a batch or a notification as one call and
replied to everything. Notifications now get 202 with no body, a batch
gets one reply per request in it, and an empty batch or a message that
is not a JSON-RPC request gets -32600 invalid request.
- The replay limit applied to a base64 body's spelling, so a binary body
under 256 KiB was truncated because its base64 is a third longer. The
limit now applies to the recorded bytes, and a cut keeps whole base64
groups.
