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. :issue:`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. :issue:`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. :issue:`503`

v8.2.1
======

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

v8.2.0
======

- Removed uses of deprecated function datetime.utcnow(). :issue:`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. :issue:`490`
- Some documentation and README updates to improve visibility of release notes. :issue:`488`
- Fixed issue where an output file could be corrupted if the process was interrupted while writing. :issue:`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.
