 - ([#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).
 - ([#13570](https://github.com/quarto-dev/quarto-cli/pull/13570)): Replace Twitter with Bluesky in default blog template and documentation examples. New blog projects now include Bluesky social links instead of Twitter.
+- ([#13716](https://github.com/quarto-dev/quarto-cli/issues/13716)): Fix draft pages showing blank during preview when pre-render scripts are configured.
