ImprovementsSection of the release
Unclear It is not known how this upload is started or whether the allow_cobalt_plinth policy allows it by default.
What
Claude Code has code that uploads files to a server. That code has changed:
It checks the upload address and headers before sending.
It retries when the server says it is busy.
It refuses credential files and Claude Code's own files.
It enforces size limits.
It reports a separate error for each file, such as a hash mismatch, a refusal or a busy server. A hash is a fingerprint used to confirm the file arrived intact.
The upload is controlled by an organization policy named allow_cobalt_plinth.
Why
This is a route for sending files from your machine to a server, and your organization's policy decides whether it may be used.
