7.0 Changelog

Version 7.0 of PDF.js Express includes many new features (including a brand new UI), and a bunch of improvements and bug fixes!

There are also a few breaking changes, which are more closely discussed in the migration guide

Breaking changes

A new and improved default UI that is structured a bit differently. The previous UI is still accessible with the constructor option ui: 'legacy'.
All APIs now take 1-indexed page numbers. Previously some APIs would take 0-indexed page numbers.
Search constants have been moved to the CoreControls namespace.

New

Updated the RubberStampCreateTool to allow the creation of custom stamps.
Updated the RubberStampCreateTool to allow setting a list of default stamps and custom stamps. These lists are used by default in the UI.
Added a count measurement tool which will track the number of count annotations on the document.
Properties and constants now consistently use the same casing throughout the WebViewer APIs. For example Namespace.MY_CONSTANT. The previous casings still remain for backwards compatibility.
Added support for displaying polyline line endings
Added AnnotationManager.getCopiedAnnotations API to get the list of annotations that are currently copied
Added a historyChanged event to AnnotationHistoryManager as well as the canUndo and canRedo functions.
Added a getContents API to the FreeText editor instance

Added a new event that is fired when the active search result has changed
