v68.0

e9352be

v68.0

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.

Security

Always use URL fetcher for HTTP redirects

Python API

default_url_fetcher() is deprecated, use the new URLFetcher class instead, see URL Fetchers for more information about URL fetchers
DocumentMetadata.generate_rdf_metadata is now a method that can be overridden instead of a parameter, see Factur-X / ZUGFeRD (Electronic Invoices) for examples to create e-invoices
