Released on 2023-04-14.
**This version is experimental, don't use it in production. If you find bugs,
please report them!**
Command-line API:
* The ``--optimize-size`` option and its short equivalent ``-O`` have been
deprecated. To activate or deactivate different size optimizations, you can
now use:
* ``--uncompressed-pdf``,
* ``--optimize-images``,
* ``--full-fonts``,
* ``--hinting``,
* ``--dpi <resolution>``, and
* ``--jpeg-quality <quality>``.
* A new ``--cache-folder <folder>`` option has been added to store temporary
data in the given folder on the disk instead of keeping them in memory.
Python API:
* Global rendering options are now given in ``**options`` instead of dedicated
parameters, with slightly different names. It means that the signature of the
``HTML.render()``, ``HTML.write_pdf()`` and ``Document.write_pdf()`` has
changed. Here are the steps to port your Python code to v59.0:
1. Use named parameters for these functions, not positioned parameters.
2. Rename some the parameters:
* ``image_cache`` becomes ``cache`` (see below),
* ``identifier`` becomes ``pdf_identifier``,
* ``variant`` becomes ``pdf_variant``,
* ``version`` becomes ``pdf_version``,
* ``forms`` becomes ``pdf_forms``.
* The ``optimize_size`` parameter of ``HTML.render()``, ``HTML.write_pdf()``
and ``Document()`` has been removed and will be ignored. You can now use the
``uncompressed_pdf``, ``full_fonts``, ``hinting``, ``dpi`` and
``jpeg_quality`` parameters that are included in ``**options``.
* The ``cache`` parameter can be included in ``**options`` to replace
``image_cache``. If it is a dictionary, this dictionary will be used to store
temporary data in memory, and can be even shared between multiple documents.
If it’s a folder Path or string, WeasyPrint stores temporary data in the
given temporary folder on disk instead of keeping them in memory.
