Release Notes

jsdom/jsdom

v15.2.0

Compare Source

• Added basic style inheritance in getComputedStyle() for the 'visibility' property. This sets the foundation for further work on inheritance, cascading, and specificity. (eps1lon)
• Added shadowRoot.activeElement.
• Added readystatechange events during document loading.
• Added a stub for form.requestSubmit(), to match our existing stub for form.submit().
• Changed el.tabIndex's default value, when no tabindex="" attribute was set, to reflect the updated specification.
• Changed the exception thrown by el.attachShadow() on something that's already a shadow host, to reflect the updated specification.
• Fixed the validation logic for <input type="range">.
• Fixed selectEl.value when no <option> is selected to return the empty string, instead of the value of the first option. (tgohn)
• Fixed various correctness issues with new FormData(formElement). (brendo)
• Fixed error messages when parsing XML to include the filename, instead of using "undefined". (papandreou)
• Fixed the logic for reflected properties to not be affected by overwriting of el.getAttributeNS() or el.setAttributeNS().
• Set canvas as an optional ``peerDependency`, which apparently helps with Yarn PnP support.
