What's Changed

• Adds initial PDF/A compliance mode (https://github.com/dompdf/dompdf/pull/3269)
• Adds data-URIs to the resource reference validation logic and handles the same as other resource reference protocols (https://github.com/dompdf/dompdf/pull/3492)
  • Note: this change requires that users of data URIs include the "data://" scheme in the list of allowed protocols.
  • Allows data-URIs to be used for @font-face declarations
• Adds support for data-URI JPEG images in Cpdf (https://github.com/dompdf/dompdf/pull/2783)
• Seeks local resources with a leading slash from the specified chroot directories if they are not found from the filesystem root (https://github.com/dompdf/dompdf/pull/3444)
• Addresses an issue preventing class-based Font Awesome usage (https://github.com/dompdf/dompdf/pull/3571)

Breaking Change

This release adds the "data://" scheme to the protocol validation rules. Installations that explicitly define the allowed protocols but do not include the "data://" protocol will no longer render data-URIs. This is a change from previous versions, where data-URIs were not processed through the validated rules. Installations that use the default validation rules included with Dompdf should see no impact.
