• Breaking change: upgraded tough-cookie, which now considers URLs like http://localhost/ to be secure contexts (per the spec), and thus will return Secure-flagged cookies for such URLs. (colincasey)
• Added customElements.getName(). (mash-graz)
• Changed the <input> element's pattern="" attribute to use the v regular expression flag, instead of u.
• Fixed jsdom.reconfigure({ url }) not updating document.baseURI or properties derived from it. This regressed in v26.1.0.
• Fixed CSS system colors, as well as the initial, inherit, and unset keywords, to resolve correctly. This is especially important since the change in v27.0.0-beta.1 to use system colors in the user agent stylesheet. (asamuzaK)
• Fixed CSS background property parsing and serialization. (asamuzaK)
• Fixed CSS color parsing and serialization inside of gradients. (asamuzaK)
• Fixed CSS display style resolution. (asamuzaK)
• Upgraded @asamuzakjp/dom-selector, which notably fixed repeated use of the :scope selector. (asamuzaK)
