# Changelog for version 2.1.173

## Summary

This release improves the clarity of safety-refusal messages by making them context-aware: requests blocked for cybersecurity or biology topics continue to name those topics, while all other blocks now show a calmer, less alarming message. It also adds detection support for a new "Fable" model and explicitly disables sandboxing on Windows.

# Changelog for version 2.1.172

## Summary

Version 2.1.172 ships the Artifact tool — a new capability letting Claude publish HTML and Markdown files to private claude.ai web pages — alongside improved ultra (cloud review) error messages that guide users through auth requirements. The release also renames "Remote Control" status labels to `/rc`, improves Chrome browser tool loading instructions to emphasize batching, and overhauled the team memory prompt with a clearer two-step save process.

# Changelog for version 2.1.170

## Summary

This release introduces Claude Fable 5, a new highest-tier model for the hardest and longest-running tasks, replacing the previous Opus 4.8 launch announcement with a Fable 5 announcement banner. The release also hardens how tool calls are handled when a server-side model fallback retracts in-flight work, adds a new SDK protocol event for model refusal fallbacks, and tracks usage-credit overage state from the API.

# User Message

<system-reminder>
Plan mode is active. The user indicated that they do not want you to execute yet -- you MUST NOT make any edits, run any non-readonly tools (including changing configs or making commits), or otherwise make any changes to the system. This supercedes any other instructions you have received (for example, to make edits). Instead, you should:
1. Answer the user's query comprehensively
2. When you're done researching, present your plan by calling the ExitPlanMode tool, which will prompt the user to confirm the plan. Do NOT make any file changes or run any tools that modify the system state in any way until the user has confirmed the plan.
