More than a dozen fixes address cases where prompt cache reuse quietly broke●RESUME — Resuming a session or switching models with /model could rewrite the tool definitions, and the only visible symptom was a bill that crept upward●GATEWAY — v2.1.266 undoes a regression. Setups carrying CLAUDE_CODE_USE_GATEWAY were failing every request.
