v8.15.1

  • Reformat with ruff.

  • Various updates to build procedures and wheel generation.

v8.15.0

  • Rebuild wheels with QPDF 11.9.0.

  • Relaxed dependency requirements on lxml, now that that project is publishing wheels for less common platforms again.

v8.14.0

  • Added new code to suppress console window from appearing on Windows in some situations when decoding JBIG2.

  • Updated GitHub Actions versions.

  • Added QPDF_FUTURE environment variable for compile-time testing of new QPDF features. This option is mainly for the developers of QPDF to confirm that pikepdf supports change they are considering in future releases; other users will not gain any benefit.

v8.13.0

  • Enabled PyPy 3.10 support.

v8.12.0

  • Rebuilt wheels with QPDF 11.8.0.

  • Improved test coverage slightly.

  • Minor performance improvement when using file streams.

  • Minor update to metadata documentation.

v8.11.2

  • Fixed handling of XMP metadata when metadata contains objects in a default namespace.

v8.11.1

  • macOS wheels are now linked against the GnuTLS crypto library instead of OpenSSL. Hopefully this will alleviate situations where the legacy crypto provider could not be loaded. #520

  • Replaced all relative imports with absolute imports.

  • Excluded lxml 5.x for Python 3.8 and 3.9, since this project is not producing wheels for 3.8 and 3.9 for the latest versions.

v8.11.0

  • Rebuilt with QPDF 11.7.0.

  • Added support for setting page boxes to a rectangle directly, e.g. page.mediabox = rectangle - previously rectangle had to manually converted to an array.

  • Fixed rendering of PDF and individual pages in Jupyter/IPython. Newer versions of these tools are now pickier about what types of data they render, and don’t render PDFs directly; we now provide SVG which works well. Requires installation of MuPDF as before.

  • Fixed rendering of inline images in Jupyter/IPython, which was not implemented.

  • Fixed build process to use new artifacts v4 actions on GitHub.

v8.10.1

  • Rebuilt with QPDF 11.6.4.

  • Replaced use of a custom C++ logger with sharing QPDF’s. It is still relayed to the Python logger.

  • Added a simpler API for adding attachments from bytes data.

  • Deprecated use of Object.parse(str) in favor of Object.parse(bytes).

v8.10.0

  • Fixed a performance regression when appending thousands of pages from one PDF to another.

  • Fixed some obscure issues with iterators over Pdf.pages that would have led to incorrect or unintuitive behavior, like partial iteration not being accounted for.

  • Using the Pdf.pages API to insert objects other pikepdf.Pdf is now deprecated. Previously, we accepted pikepdf.Dictionary that had its /Type set to /Page. Now, one must wrap these dictionaries in pikepdf.Page().

  • Added type hints that pikepdf.Object can be implicitly converted to float and int.

v8.9.0

  • Overhauled documentation. Previously the documentation could only be generated in an environment where pikepdf was compiled and installed, since generating the final result depended on executing pikepdf. Now, these dynamic features are removed and the documentation is static. All documentation that was defined in C++ has been pulled out and defined in Python stub files instead, which means compiled binaries are no longer needed to access documentation. This change simplifies the generation of documentation and makes it easier for IDEs to look up function signatures.

  • Similarly, typing is now defined only in Python stub files.

v8.8.0

  • Added new pikepdf.canvas module with rudimentary content stream creation functions.

v8.7.1

  • Fixed pikepdf.Matrix.rotated() so it now rotates in the advertised direction.

v8.7.0

  • pikepdf.PdfMatrix is now deprecated, in favor of pikepdf.Matrix. The former, unfortunately, implemented some operations backwards compared to the PDF reference manual. The new class fixes these issues, and adds more functionality, promoting transformation matrix to first class objects. PdfMatrix is now deprecated and will be removed in the next major release.

  • Improve behavior around truthiness of pikepdf.Name.

v8.6.0

  • Implemented Page.artbox and Page.bleedbox to access these page dimension boxes.

v8.5.3

  • Fixed exception on certain PdfImage.__repr__ when the image’s mode was invalid.

  • Fixed some minor issues that caused code coverage to miss some covered lines.

  • Removed some unused code.

v8.5.2

  • Rebuilt wheels with libqpdf 11.6.3, which solves a potential data loss issue, albeit in rare circumstances. See QPDF issue #1050.

  • Fixed unclear return values of pikepdf._core.set/get* functions. The set functions now return the current value.

  • Fixed minor typing issues.

v8.5.1

  • Added building of Python 3.12 aarch64 images.

  • Added building of musllinux_1_2 aarch64 images.

  • Tweaked exception handler of atomic_overwrite.

v8.5.0

  • We now require Pillow 10.0.1, due a serious security vulnerability in all earlier versions of that dependency. The vulnerability concerns WebP images, which are likely not involved in PDF processing, but we have updated the dependency anyway as a precaution. As a consequence, we no longer build binary wheels for PyPy 3.8. CPython 3.8 is still supported on all platforms.

  • The embedded files/attachments API now supports describing the relationship of the attached file (AFRelationship).

v8.4.1

  • Fixed an issue with a monochrome that decoded with colors inverted. #517

v8.4.0

  • Added support for musllinux_1_2 (Alpine Linux 3.16) on x64.

v8.3.2

  • Added _core.pyi typing hints, which were missing from wheels.

v8.3.1

  • Fixed saving file opened from BytesIO object on Windows. #510

v8.3.0

  • Mark Python 3.12 as supported and release wheels for it.

v8.2.3

  • Added a build test for Python 3.12 pre-release versions.

  • Marked a test as xfail that currently fails on Python 3.12.

v8.2.2

  • Added docs/ directory back to source distribution. #503

v8.2.1

  • Fixed a build issue where pikepdf would install its C++ source files into the site-packages directory. #447

v8.2.0

  • Removed uses of deprecated function datetime.utcnow(). #499

  • Adjusted timeline of potentially flaky hypothesis test.

  • Various documentation fixes. Thanks @m-holger.

  • PyPy 3.10 is now supported on some platforms.

  • PyPy 3.8 support will be dropped in the next major release.

v8.1.1

  • Fixed a Unicode test that randomly fails on Windows.

v8.1.0

  • Not released due to build failure.

  • Fixed sdist, which was mysteriously missing some files that were previously included. #490

  • Some documentation and README updates to improve visibility of release notes. #488

  • Fixed issue where an output file could be corrupted if the process was interrupted while writing. #462

v8.0.0

  • master branch renamed to main.

  • QPDF 11.5.0 is now required.

  • Some other Python dependencies have been updated.

  • Dropped setuptools-scm in favor of a manually set version number and script to update it. This change was necessary to support delegating part of the build to Cirrus CI.

  • Adjusted stream preview (with __repr__) so it does not attempt to decompress very long streams.

  • Fixed error when attempting to convert XMP metadata to DocumentInfo when the author was omitted.

  • Added a method to add items to the document table of contents.

  • Previously, we built all Apple Silicon (aarch64) wheels as a manual step, causing errors and delays in their release compared to other wheels. We now build them automatically on Cirrus CI.

  • Changed to building manylinux-aarch64 wheels on Cirrus CI.

  • Since Pillow (Python imaging library), a major dependency, has dropped support for 32-bit wheels on Windows and Linux, we have done the same. You can still build 32-bit versions from source.

  • Some documentation changes and improvements. Thanks @m-holger.
