The authz, identity, and notification modules are now exposed as public API on the annotator page global.
The notifier, identityPolicy and authorizationPolicy are now retrieved from component registry. It should now be possible to register alternative implementations.
Performance of the highlighter should be slightly improved.
Showing the viewer with a mouse hover should be much faster when there are many overlapping highlights. (#520)
The getGlobal() function of the util module has been removed and Annotator should now work with Content Security Policy rules that prevent eval of code.
The markdown extension has been upgraded to require and support version 1.0 or greater of the Showdown library.

Fix a bug in the ui.filter extension so that the filters option now works as specified.
Make the highlighter work even when the global document symbol is not window.document.
Fix an issue with the editor where adding custom fields could result in fields appearing more than once. (#533)
With the autoViewHighlights options of the viewer, don't show the viewer while the primary mouse button is pressed. Before, this prevention applied to every button except the primary button, which was not the intended behavior.
