What

Claude Code can receive a setting from the server that controls how events are uploaded in batches. That setting has been renamed:

  • Server field: joint_upload is now event_batch_upload. The new field is read from a different place, so the old key no longer has any effect.
  • Internal policy key: jointUpload is now eventBatchUpload.
  • Refusal check: the check for whether this upload path is refused is now its own method, ridesAreOff().

Why

A server that still sends joint_upload will no longer turn on batched uploads. Only event_batch_upload does.
