 - ([#10532](https://github.com/quarto-dev/quarto-cli/issues/10532)): Quarto changed default of `--headless=old` to `--headless` as [Chrome 132 has removed old headless mode](https://developer.chrome.com/blog/removing-headless-old-from-chrome) and only support new mode. For using old mode, `QUARTO_CHROMIUM` could be set to a [new `chrome-headless-shell` binary](https://developer.chrome.com/blog/chrome-headless-shell) or too an older chrome version (between 128 and 132) and `QUARTO_CHROMIUM_HEADLESS_MODE` set to `old` for using old headless mode with that compatabitle version.
 - ([#10961](https://github.com/quarto-dev/quarto-cli/issues/10961)): Add more information on which Chrome Headless will be used in `quarto check install`. This is helpful to help debug mermaid issues.
