Version v3.3.0 (released 2025-08-25)

• fix(ext): avoid unecessary assert error

  • The check for an already registered previewer was just checking by name, instead of also verifying if the registered object is the same instance.

  • Instead of an assertion, we raise a RuntimeError with information about the already registered and conflicting previewer instances.

• feat(pdfjs): open links in new tabs

  • Sets by default in the PDF.js settings that links open in a new tab. The old behaviort was that when clicking a link inside a previewed PDF, the navigation happens inside the iframe, which then because of the X-Frame-Options: sameorigin setting blocked the content.

• feat(pdfjs): disable sandboxed JS execution by default

  • Adds a new PREVIEWER_PDF_JS_ENABLE_SCRIPTING config variable for allowing to disable the sandboxed JS execution support in PDF.js. This config is by default set to False.
