 # Changelog
 
 
+## 4.20.0 (2023-09-10)
+
+- Updated PDFium from `5975` to `5989`.
+This release backports some key fixes/improvements from the development branch:
+- [V8/XFA] Fixed XFA init. This issue was caused by a typo in a struct field. Thanks to Benoît Blanchon.
+- [ctypesgen fork] Prevent setting nonexistent struct fields.
+- [V8/XFA] Expose V8/XFA exclusive members in the bindings file by passing ctypesgen the pre-processor defines in question.
+- Fixed some major non-API implementation issues with multipage rendering:
+  * Avoid full state data transfer and object re-initialization for each job. Instead, use a pool initializer and exploit global variables. This also makes bytes input tolerable for parallel rendering.
+  * In the CLI, use a custom converter to save directly in workers instead of serializing bitmaps to the main process.
+- Set pdfium version fields to unknown for `PDFIUM_PLATFORM=none` (sdist). This prevents encoding a potentially incorrect version. Also improve CLI version print.
+- Fixed sourcebuild with system libraries.
+- Fixed RTD build (`system_packages` option removal).
+- Attempt to fix automatic GH pages rebuild on release.
