# v9.5.2

- Fixed an issue where temporary files could be left behind when using allow_overwriting_input=True and a SIGINT is sent while the file is being flushed to disk, or generally within a specific timing window.

- Fixed an issue via OCRmyPDF by replacing an invalid Document Info dictionary with a valid dictionary.

# v9.5.1

- Bump version to address sigstore build issues.

- Pillow dropped PyPy 3.9 so we’re dropping it too.

# v9.5.0

- Created setter for Outline management to make manipulating outlines easier. Thanks @Zhongheng-Cheng for this contribution. #636

- pikepdf now sets XMP properties as subelements instead of inline properties, in line with the XMP specification. Thanks @federicobond. #628

- pikepdf an issue with converting certain images to PIL. Thanks @DaveDeCaprio. #632

- Added a new `pikepdf.exceptions` module which organizes all exceptions more conveniently.

- pikepdf now tries harder to extract corrupt images in a PDF when they are found.

- Fixed an issue where an exception handler referred to an object not in scope, causing another exception. Thanks @dhazelett. #627

- Dropped a comment about an unsupported dependency.

# v9.4.2

- Internal type assertion error messages from qpdf that previously triggered a RuntimeError will now raise a PdfError. Generally these errors only occur in corrupted files.

- When we are updating XMP in the processing of saving, errors from updating XML are wrapped differently to clarify the context in which the error occurs.

# v9.4.1

- Fixed a process abort in JBIG2 handling related to cleanup of Python objects owned by C++ code.

- Fixed inconsistent behavior when setting metadata records to an empty value. #622

# v9.4.0

- Added missing Python 3.13 wheels for a few platforms that were missing them, mainly ARM Linux, musllinux/Alpine, and Windows.

- Since Homebrew has ended support for macOS 12, macOS 13 is now the minimum requirement for Intel macOS.

- Suppressed some spurious warnings during build tests.

# v9.3.0

- Integrated OSS Fuzz.

- Prevented generation of PDF date strings with invalid trailing apostrophes, while still accepting them.

- Improved error message on parsing invalid date strings.

- Dropped support for Python 3.8 (end of life October 2024).

# v9.2.1

- Fixed some inconsistencies with the pikepdf.Rectangle class. #605

- Python 3.13 with free-threading added to test matrix.

- Removed wheel package as build requirement since modern packing no longer needs it.

# v9.2.0

- Updated C++/Python exception translation to new pybind11 2.12.0+ protocol, fixing possible undefined behavior in multithreaded applications.

- pybind11 2.12.0 is now required.

- qpdf 11.9.1 is now used to build wheels.

- Modernized copyright information to REUSE.toml specification.

- Added a new test file for a rare case, CCITT with EndOfLine=True. Thanks @ekordas. #602, #601

# v9.1.2

- Fixed handling of CalRGB and CalGray images with palettes.

- Fixed a test suite failure when numpy 2.1 is installed. #603

- Prevented use of setuptools 72+ since it seems to introduce build errors.

- Added a missing #include header. #600

# v9.1.1

- Fixed an issue where small floating point values would be recorded in scientific notation, contrary to the PDF specification. #598

- Fixed some false positive warnings on Windows C++ compilers.

- Improved support for Python 3.13 pre-release.

# v9.1.0

- Fixed a potential resource leak if we opened a file to read it as a PDF but it was not a valid PDF.

- When overwriting an existing PDF with `Pdf.save()`, pikepdf now attempts to retain the original file permissions and ownership.

- Fixed missing return type for PageList.Extend. #592

- Fixed exception if `jbig2dec --version` exists but valids to return a version number.

- Fixed tests on Python 3.13 pre-release. Thanks @QuLogic.

- Changed all references of “QPDF” to “qpdf”, its new spelling. Thanks @m-holger.

# v9.0.0

- Removed deprecated pikepdf.PdfMatrix. Use pikepdf.Matrix instead.

- Removed deprecated pikepdf._qpdf submodule.

- Pdf.pages no longer coerces PDF dictionaries to page objects. You must explicitly insert/add pikepdf.Page objects.

- pikepdf.Object.parse() no longer accepts string input; only bytes are allowed.

- macOS 12 is our minimum supported version for x86_64, and macos 14 is our minimum supported version for ARM64/Apple Silicon. v8 accidentally ended support for older versions at some point - this change is formalizing that. Efforts were made to continue support for older verions, but it is not sustainable.

- We now generate binary wheels for musllinux-aarch64 (Alpine ARM64).
