weasyprint 68.0

v68.0

on Python PyPI

This is a security update (CVE-2025-68616).

We strongly recommend to upgrade WeasyPrint to the latest version if you use the default_url_fetcher function in your custom URL fetcher, or if you use the allowed_protocols parameter of the default_url_fetcher function.

Read about this release on our blog.
