Foxit PDF SDK for Web 11.0.0 ​

Release date: June 30, 2025

Breaking changes ​

Form module refactor ​

Version 11.0 fully refactors the form module (including how form scripts run) for faster rendering, more native-looking visuals, and richer APIs. This release is not backward compatible.

Removed APIs

The following legacy form classes and APIs were removed; some are replaced by the new form APIs:

  • PDF.form.PDFControl
  • PDF.form.PDFField
  • PDF.form.PDFForm
  • PDFDoc.loadPDFForm

Impact

  • API changes: Code using the APIs above must migrate to the new form APIs.
  • Rendering: Form fields are no longer DOM-based; the PDF render engine draws them directly.
  • PDF JavaScript:
    • Execution runs in a Web Worker for main-thread safety.
    • Core PDF JavaScript APIs are implemented in C++/WebAssembly.

Replacement

  • Use:
    • PDF.form.PDFForm
    • PDF.form.PDFFormField
    • PDFViewCtrl.form.FormFillerService
    • addons.form_designer_addon
  • See the PDF Form API Migration Guide for details.

Signature workflow refactor ​

Signing and verification for AcroForm and XFA were refactored for clearer, more maintainable APIs.

Deprecated APIs

  • PDFUI.registerSignatureFlowHandler
  • PDFUI.setVerifyHandler

Impact

  • Still available in 11.0 but will be removed later. Migrate if your app depends on them.

Replacement

Action system refactor ​

The legacy standalone Action API architecture is deprecated in favor of a unified action and event model.

Deprecated API

  • PDF.actions.action

Impact

  • Still available in 11.0 but will be removed later.

Replacement

Bookmark API cleanup ​

All bookmark APIs from before 10.0 were removed in this release.

Impact

  • Apps still using legacy bookmark APIs will not work on 11.0.

Replacement
