Version 59.0b1

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.

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

- Do not repeat a block’s margin-top or padding-top after a page break.
- Performance problem with large tables split across many pages.
- Anchors and hyperlinks areas now follow CSS transforms. Since PDF links have to be axis-aligned rectangles, the bounding box is used. This may be larger than expected with rotations that are not a multiple of 90 degrees.

Version 0.14

Released on 2012-08-03.

Add a public API to choose media type used for @media. (It still defaults to print). Thanks Chung Lu!

Bug fix: crash in PDF outlines for some malformed HTML documents

Version 0.12

Add support for collapsed borders on tables. This is currently incompatible with repeating header and footer row groups on each page: headers and footers are treated as normal row groups on table with border-collapse: collapse.
Add url_fetcher to the public API. This enables users to hook into WeasyPrint for fetching linked stylesheets or images, eg. to generate them on the fly without going through the network. This enables the creation of Flask-WeasyPrint.

Version 0.11

Released on 2012-07-04.

Add support for the width, min-width, max-width, height, min-height and max-height properties in @page. The size property is now the size of the page’s containing block.
Switch the Variable Dimension rules to the new proposal. The previous implementation was broken in many cases.
The image-rendering, transform, transform-origin and size properties are now unprefixed. The prefixed form (eg. -weasy-size) is ignored but gives a specific warning.

Version 0.10

Released on 2012-06-25.

Add get_png_pages() to the public API. It returns each page as a separate PNG image.

The default UA stylesheet sets a matching bookmark level on all <h1> to <h6> elements.

Version 0.8

Released on 2012-05-07.

Switch from cssutils to tinycss as the CSS parser.
Switch to the new cssselect, almost all level 3 selectors are supported now.

Backward incompatible: completely change the Python API. See the documentation: https://weasyprint.readthedocs.io/en/latest/tutorial.html#as-a-python-library
Backward incompatible: Proper margin collapsing. This changes how blocks are rendered: adjoining margins “collapse” (their maximum is used) instead of accumulating.
Support images in embed or object elements.
Switch to pystacia instead of PIL for raster images
Add compatibility with CPython 2.6 and 3.2. (Previously only 2.7 was supported)
Many bug fixes

Version 0.5

Released on 2012-02-08.

Support text-align: justify, word-spacing and letter-spacing.
Partial support for CSS3 Paged Media: page size and margin boxes with page-based counters.

Version 0.1

Released on 2011-10-28.

First packaged release. Supports “simple” CSS 2.1 pages: there is no support for floats, tables, or absolute positioning. Other than that most of CSS 2.1 is supported, as well as CSS 3 Colors and Selectors.
