Release 0.7.1 further reduces the minified size of the xtypejs core library, and is released together with new type introspection functionality from the new xtypejs-extension-introspection extension. This new functionality makes it easy to produce much friendlier type and data validation reporting, useful for UIs, user messaging, error reporting, as well as other data and user input validation scenarios. The new extension both extends and replaces the old xtypejs-extension-typename-utils extension without any loss of existing functionality. Please see the Using Type Introspection topic under the Guide section of the website, as well as the Introspection section under the API section for full details on the new introspection features.
