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.

New features

#1853, #1854: Reduce PDF size, with financial support from Code & Co.
#1824, #1829: Reduce memory use for images
#1858: Add an option to keep hinting information in embedded fonts

Bug fixes

#1855: Fix position of emojis in justified text
#1852: Don’t crash when line can be split before trailing spaces
#1843: Fix syntax of dates in metadata
#1827, #1832: Fix word-spacing problems with nested tags

Documentation

#1841: Add a paragraph about unsupported calc() function
