DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Disabled: Output Style Customization#

  • Issue: The output style feature (educational, hands-on modes) has been temporarily disabled
  • Cause: The feature is undergoing improvements and has been disabled to prevent inconsistent behavior
  • Resolution: The system now uses the default interaction style for all responses. Custom output styles configured in settings will not take effect until this feature is re-enabled in a future release

Anthropic’s official release notes

Published verbatim by Anthropic for v1.0.80. Text is unmodified from the upstream changelog. Everything else on this page came out of the bundle instead, which is why the two lists don't match.

  • UI improvements: Fix text contrast for custom subagent colors and spinner rendering issues
System prompt

The system prompt was not captured for this release, so this page cannot say whether it moved.
