 - `PdfPage.get_objects()`: Don't register pageobjects as children, because they don't need to be closed by the caller when part of a page. This avoids excessive caching of weakrefs that are not cleaned up with the object they refer to.
 - Fixed another dotted filepath blunder in the `extract-images` CLI. (The `PdfImage.extract()` API is not affected this time.)
 - Fixed installation with reference bindings (`PDFIUM_BINDINGS=reference`) by adding a missing `mkdir` call. (In older versions, this can be worked around by unpacking the sdist and creating the missing directory manually before installation.)
+- Fixed sourcebuild on windows by syncing patches with pdfium-binaries.
 - Updated test expectations: due to changes in pdfium, some numbers are now slightly different.
 - Fixed conda packaging: It is now required to explicitly specify `-c defaults` with `--override-channels`, presumably due to an upstream change.
 - Autorelease: Swapped default condition for minor/patch update, as pypdfium2 changes are likely more API-significant than pdfium updates. Added ability for manual override.
