• Fixed: Node.prototype.contains to always return a boolean. This was a regression in 3.1.1. (@Joris-van-der-Wel)
• Fixed: Document.prototype no longer contains its own ownerDocument getter, instead correctly delegating to Node.prototype.
• Fixed: some edge cases regarding running <script>s in browserified jsdom.
• A couple fixes from updated dependencies (although you would have gotten these anyway with a fresh install, due to floating version specifiers):
  • csstyle minimum version bumped from 0.2.21 to 0.2.23, fixing handling of 0 when setting numeric CSS properties and parsing of shorthand font declarations.
  • parse5 minimum version bumped from 1.3.1 to 1.3.2 to, fixing the parsing of <form> elements inside <template> elements.
