+
+The package is now ESM only, and requires Node.js 22.12 or later
+
+#### When you will see a difference
+
+Only if you load this package with `require()`, or build on Node.js 20 or earlier. If you already `import` it, nothing changes.
+
+#### What changes
+
+The package no longer ships a CommonJS build. `require("@portabletext/react-pdf")` will fail, where before it resolved to `dist/index.cjs`. Use `import` instead, or a dynamic `await import()` from a CommonJS file.
+
+This brings the package in line with the rest of the Portable Text packages, which are already ESM only.
+
+Node.js 20 reached end of life in April 2026. The package previously declared no `engines` range at all, so nothing was enforced.
