 - ([#13524](https://github.com/quarto-dev/quarto-cli/issues/13524)): Add support for Plausible Analytics via `plausible-analytics` configuration option. Users can either paste their Plausible script snippet directly in YAML or provide a path to a file containing the snippet using `plausible-analytics: { path: _plausible_snippet.html }`.
 - ([#13525](https://github.com/quarto-dev/quarto-cli/issues/13525)): Algolia Insights now uses privacy-friendly defaults: `useCookie: false` with random session tokens when cookie consent is not configured. When `cookie-consent: true` is enabled, Algolia scripts are deferred and only use cookies after user grants "tracking" consent, ensuring GDPR compliance.
-- ([#13547](https://github.com/quarto-dev/quarto-cli/issues/13547))`cookie-content: { type: express }` is now the default. Previously it was `type: implied`. It now means this will block cookies until the user expressly agrees to allow them (or continue blocking them if the user doesn’t agree).
