Release Notes

21.0.0

A potentially-breaking bug fix:

• Fixed the window, document, location, and top properties of Window to be non-configurable. (ExE-Boss)

Other changes:

• Added support for <input type=image> submitting forms. (jenseng)
• Added the location setter to the Window object, which forwards to the location.href setter. Setting the URL is still only implemented for fragment navigations, however. (ExE-Boss)
• Fixed defer="" <script> elements that are added after DOMContentLoaded to execute, instead of being skipped.
• Fixed selectElement.selectedOptions being incorrect when optionElement.selected is set. This was a regression introduced in v20.0.1. Unfortunately this also reverts the performance improvement when appending <option> elements that was introduced then. (eps1lon)
• Fixed the self, locationbar, menubar, personalbar, scrollbars, statusbar, toolbar, frames, parent, external, length, and screen properties of Window to be replaceable: that is, setting them will override their values, instead of having the new value be ignored. (ExE-Boss)
• Fixed a few issues with JSOM.fromURL() in the browser build of jsdom. (LungZeno)

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