Major Changes
Form Module Refactor
The form module (including Form scripting execution) has been completely refactored in version 11.0 to deliver faster rendering, native-like visual fidelity, and more robust API capabilities. These changes introduce breaking updates and are not backward-compatible with old versions.
Removed APIs
The following legacy form-related APIs have been removed and replaced with a new form architecture:
PDF.form.PDFControlPDF.form.PDFFieldPDF.form.PDFFormPDFDoc.loadPDFForm
Impact
API Changes: Any code relying on the removed interfaces must be updated to the new APIs.
Rendering Behavior Change: Form fields are no longer rendered using separate DOM elements. They are now drawn directly by the PDF rendering engine.
Form JavaScript Scripting Architecture Upgrade:
Form JavaScript execution context has been migrated to
Web Worker, ensuring the main thread security operations.Core Form JavaScript APIs have been refactored to
C++/WebAssemblyimplementation.
Replacement
Use the following new form-related APIs:
PDF.form.PDFFormPDF.form.PDFFormFieldPDFViewCtrl.form.FormFillerServiceaddons.form_designer_addon
Refer to the PDF Form API Migration Guide in the Developer Guide for complete migration details.
Signature Workflow Refactor
The signature and verification workflow for both standard AcroForm and dynamic XFA forms has been redesigned for improved usability and maintainability.
Deprecated APIs
PDFUI.registerSignatureFlowHandlerPDFUI.setVerifyHandler
Impact
These APIs remain available in version 11.0 for backward compatibility but will be removed in a future release. Please plan your migration accordingly.
Replacement
Use the new signature workflow interfaces:
PDF.form.signatureServicePDF.form.SignatureWorkflowService
Refer to the Signature Workflow API Migration Guide in the Developer Guide for full details and examples.
Action Module Refactor
Deprecated old action API system in favor of more efficient approaches.
Deprecated APIs
PDF.actions.action
Impact
These APIs are still available in version 11.0 for backward compatibility but will be removed in a future release. If your application depends on these APIs, we strongly recommend migrating to the new API system now.
Replacement
Refer to the
Upgrade Guide for Action APIsin the Developer Guide for instructions on migrating to the new Action API system.
Legacy Bookmark API Cleanup
All legacy bookmark-related APIs deprecated in earlier versions have now been fully removed.
Impact
Any applications still using the old bookmark APIs will no longer function correctly in version 11.0.
Replacement
Refer to the Bookmark API Migration Guide in the Developer Guide for the proper migration path.
