What
In cloud sessions, Claude Code had an optional second way to upload client events: a streaming connection, with its own state reported when the server rejected it. That path has been removed. Events now go only through the regular upload, where each batch is sent as a separate request.
Why
There is one upload route for these events instead of two.
