Claude Code v2.1.185 changes the stream stall message text
On June 20, 2026 at 20:59 UTC, Anthropic released Claude Code v2.1.185 — an exclusively UX patch that improves communication with the user during API response stalls.
What exactly changed
The old message read “No response from API · Retrying in …”, which could appear to users as a system error. The new message “Waiting for API response · will retry in …” explicitly communicates that Claude Code is waiting for a response and will automatically retry — without any need for manual intervention.
Along with the text change, the message activation threshold was extended from 10 to 20 seconds of silence. By comparison, the previous version displayed the warning twice as fast, which unnecessarily alarmed users during normal network delays.
Fast release cycle — no under-the-hood changes
This is the only release for June 20, the day after v2.1.183 (June 19). Neither the model, nor API endpoints, nor retry logic were touched — this is purely an improvement to the user experience during extended waits.
Why this matters
In developer tools, message clarity directly affects trust. The difference between “No response” and “Waiting for response” is semantically small, but in practice it reduces false alarms and manual session restarts — especially for complex requests that take longer to process context.
Frequently Asked Questions
- What is the stream-stall hint and why was it changed?
- The stream-stall hint is a message shown to the user when the API stops sending data for an extended period. The old message 'No response from API · Retrying in …' sounded like an error, while the new 'Waiting for API response · will retry in …' more clearly communicates that the system is waiting and will automatically retry.
- Does v2.1.185 change anything in the Claude Code model or API?
- No. This is purely a UX patch — the only changes are the message text and the activation threshold (10 → 20 seconds), with no modifications to the model, API endpoints, or retry logic.
- How often does Anthropic release new versions of Claude Code?
- The pace is fast: v2.1.183 was released on June 19, and v2.1.185 already on June 20, 2026 — meaning Anthropic regularly ships incremental patches daily or every other day.
