That data now includes which model was in use and whether a note about the zsh shell was in the prompt, plus some extra details taken from the command and its output. It no longer reports a zsh no-match error field.\n\n**Why**\n\nThis changes only the usage data sent in the background. Nothing changes in how commands run or what you see.\n\n- Area: Telemetry\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
