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.

Claude Code v2.1.166

  • --bg conflict error now correctly says --cloud instead of --remote: "Use claude --cloud '<task>' directly to start a cloud session." (search for "--bg and --cloud are different backends")
  • Policy limits cache telemetry at first prompt now additionally reports cache_age_ms and would_fail_closed, giving Anthropic better visibility into whether rate-limit enforcement would have failed due to a stale cache. (search for "would_fail_closed")
  • Shell allow-rule telemetry is now fired at initialization (tengu_shell_allow_rules_at_init) so rule coverage is captured even when no rules are added interactively during the session. (search for "tengu_shell_allow_rules_at_init")
