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 v2.1.70

  • The coral_reef_sonnet client data flag was added, checked via YgA() — this may gate future model-related behavior (search for "coral_reef_sonnet")
  • A kairosActive flag was added to session telemetry, tracked as is_assistant_mode in analytics (search for "kairosActive")
  • The telemetry event tengu_session_quality_classification was replaced by tengu_session_file_read (search for "tengu_session_file_read")
  • The "server" subcommand infrastructure (including WebSocket server, session management, auth tokens, direct-connect protocol, and cc+unix:// URL scheme) has been removed, suggesting the standalone server mode has been deprecated in favor of the CCR bridge architecture
