+## 5.7.6
+**`(fix):`** Fix docs preview server showing "ready" message when the server process
+crashes on startup. The CLI now exits with a clear error message instead.
+
+
+**`(fix):`** On Windows, recover critical standalone node_modules packages (next,
+react-dom, styled-jsx) when symlink resolution fails due to long .pnpm
+directory names. The CLI now scans the .pnpm store and copies packages
+directly as a fallback.

 ## 5.7.5
 **`(fix):`** Send `customDomains` when publishing docs translations so FDR mirrors the translated blob to every URL the docs are published to. Previously translations were only written under the canonical fern URL, so docs sites served from a custom domain with a basepath (e.g. `buildwithfern.com/learn`) 404'd on every localized page.
