Release Notes

14.0.0 (from changelog)

Breaking changes:

• JSDOM.fragment() now creates fragments whose document has no browsing context, i.e. no associated Window. This means the defaultView property will be null, resources will not load, etc.
• JSDOM.fragment(), called with no arguments, now creates a DocumentFragment with no children, instead of with a single child text node whose data was "undefined".

Other changes:

• Fixed a regression in v13.2.0 when calling element.blur() on a focused element.
• Fixed inserting <link> elements into documents with no browsing context to no longer crash if the originating JSDOM was configured to fetch the resource. Now, per spec, <link> elements only attempt to fetch if they are browsing-context connected.
• Fixed <template> elements to have the correct semantics, of using a separate browsing-context-less document to store its contents. In particular this means resources will not be fetched for elements inside the <template>, as per spec.

Does any of this look wrong? Please let us know.
