Significantly improved and sped up getComputedStyle(). Computed value rules are now applied across a broader set of properties, and include fixes related to inheritance, defaulting keywords, custom properties, and color-related values such as currentcolor and system colors. (@asamuzaK)
Fixed CSS 'background' and 'border' shorthand parsing. (@asamuzaK)
Node.js v22.13.0+ is now the minimum supported v22 version (was v22.12.0+).
Other changes:
Overhauled the CSSOM implementation, replacing the @acemir/cssom and cssstyle dependencies with fresh internal implementations built on webidl2js wrappers and the css-tree parser. Serialization, parsing, and API behavior is improved in various ways, especially around edge cases.
Added CSSCounterStyleRule and CSSNamespaceRule to jsdom Windows.
Added cssMediaRule.matches and cssSupportsRule.matches getters.
Added proper media query parsing in MediaList, using css-tree instead of naive comma-splitting. Invalid queries become "not all" per spec.
Added blob.text(), blob.arrayBuffer(), and blob.bytes() methods.
Improved getComputedStyle() to account for CSS specificity when multiple rules apply. (@asamuzaK)
Improved synchronous XMLHttpRequest performance by using a persistent worker thread, avoiding ~400ms of setup overhead on every synchronous request after the first one.
Improved performance of node.getRootNode(), node.isConnected, and event.dispatchEvent() by caching the root node of document-connected trees.
Fixed getComputedStyle() to correctly handle !important priority. (@asamuzaK)
Fixed document.getElementById() to return the first element in tree order when multiple elements share the same ID.
Fixed <svg> elements to no longer incorrectly proxy event handlers to the Window.
Fixed FileReader event timing and fileReader.result state to more closely follow the spec.
Fixed a potential hang when synchronous XMLHttpRequest encountered dispatch errors.
Fixed compatibility with environments where Node.js's built-in fetch() has been used before importing jsdom, by working around undici v6/v7 incompatibilities.
Overhauled resource loading customization. See the new README for details on the new API.
Added MIME type sniffing to <iframe> and <frame> loads.
Regression: WebSockets are no longer correctly throttled to one connection per origin. This is a result of the bug at nodejs/undici#4743.
Fixed decoding of the query components of <a> and <area> elements in non-UTF-8 documents.
Fixed XMLHttpRequest fetches and WebSocket upgrade requests to be interceptable by the new customizable resource loading. (Except synchronous XMLHttpRequests.)
Fixed the referrer of a document to be set correctly when redirects are involved; it is now the initiating page, not the last hop in the redirect chain.
Fixed correctness bugs when passing ArrayBuffers or typed arrays to various APIs, where they would not correctly snapshot the data.
Fixed require("url").parse() deprecation warning when using WebSockets.
Fixed <iframe>, <frame>, and <img> (when canvas is installed) to fire load events, not error events, on non-OK HTTP responses.
Improved CSS parsing by switching to @acemir/cssom, including support for nested selectors, nested declarations, layer statements, and improved at-rule validation. (@acemir)
Fixed some selector cache invalidation issues where changes to attributes were not being picked up. (@asamuzaK)
Fixed package.json"engines" field to reflect the new minimum Node.js versions needed to run jsdom, as noted in the changelog for v27.0.1.
This release inadvertently raised the minimum Node.js version from v20.0.0 to v20.19.0+, v22.12.0+, v24.0.0+. (This happened via a dependency update.) This probably should have been a breaking (major) change, instead of happening in a patch version, since it prevents using earlier Node.js versions.
After further testing, we found that most of our development dependencies also require these versions, and so it's not feasible for the jsdom project to support earlier Node.js versions. (For example, our testing frameworks will not run on them.) If you need to use such earlier versions, or otherwise are working in an environment which gives related errors such as ERR_REQUIRE_ESM, then please stick with the v26.1.0 release of jsdom. (Noting, of course, that such versions are unsupported, and we will not respond to bug reports opened against them.)
Subsequent jsdom releases will explicitly require these minimum Node.js versions, and will have CI testing to ensure that the minimum version is not accidentally raised again.
Normal changelog:
Fixed some regressions in CSS selectors. Most such regression fixes were done in a minor update of a dependency, and thus available for all fresh installs of v27.0.0. However, one related to class="" attribute changes is only possible with a new version of jsdom. (@asamuzaK)
Added a variety of event constructors, even though we do not implement their associated specifications or ever fire them: BeforeUnloadEvent, BlobEvent, DeviceMotionEvent (omitting requestPermission()), DeviceOrientationEvent (omitting requestPermission()), PointerEvent, PromiseRejectionEvent, and TransitionEvent.
Added movementX and movementY to MouseEvent. (These are from the Pointer Lock specification, the rest of which is not implemented.)
"jsdomError" events are now documented, with specific type properties and other properties that depend on the type.
sendTo() was renamed to forwardTo().
The jsdomErrors option to forwardTo() can be used to control which errors are sent to the Node.js console. This replaces the previous omitJSDOMErrors boolean option.
"jsdomError"s for failed XMLHttpRequest fetches are no longer emitted.
The values that are printed when forwarding "jsdomError"s to the Node.js console are streamlined.
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)
Upgraded cssstyle, which brings along many improvements and fixes to the CSSStyleDeclaration object and its properties.
Updated the user agent stylesheet to be derived from the HTML Standard, instead of from an old revision of Chromium.
Changed element.click() to fire a PointerEvent instead of a MouseEvent.
Changed certain events to be passive by default.
Changed the <input> element's pattern="" attribute to use the v regular expression flag, instead of u.
Fixed many specification conformance issues with the Window object, including named properties and changing various data properties to accessor properties.
Fixed document.createEvent() to accept a more correct set of event names.
Fixed the ElementInternals accessibility getters and setters. (They were introduced in v23.1.0, but due to inadequate test coverage never actually worked.)
Fixed using Object.defineProperty() on certain objects, such as HTMLSelectElement instances.
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. (@asamuzaK)

##### Changes since 26.1.0
- Node.js v20 is now the minimum supported version.

- Upgraded [`tough-cookie`](https://www.npmjs.com/package/tough-cookie), which now considers URLs like `http://localhost/` to be secure contexts (per [the spec](https://w3c.github.io/webappsec-secure-contexts/#is-origin-trustworthy)), and thus will return `Secure`-flagged cookies for such URLs. ([@​colincasey](https://github.com/colincasey))
- Upgraded [`cssstyle`](https://github.com/jsdom/cssstyle), which brings along many improvements and fixes to the `CSSStyleDeclaration` object and its properties.
- Updated the user agent stylesheet to be derived from the HTML Standard, instead of from an old revision of Chromium.

- Fixed CSS `display` style resolution. ([@​asamuzaK](https://github.com/asamuzaK))
##### Changes since 27.0.0-beta.3

This release inadvertently raised the minimum Node.js version from v20.0.0 to v20.19.0+, v22.12.0+, v24.0.0+. (This happened via a dependency update.) This probably should have been a breaking (major) change, instead of happening in a patch version, since it prevents using earlier Node.js versions.
After further testing, we found that most of our development dependencies also require these versions, and so it's not feasible for the jsdom project to support earlier Node.js versions. (For example, our testing frameworks will not run on them.) If you need to use such earlier versions, or otherwise are working in an environment which gives related errors such as
ERR_REQUIRE_ESM, then please stick with the v26.1.0 release of jsdom. (Noting, of course, that such versions are unsupported, and we will not respond to bug reports opened against them.)Subsequent jsdom releases will explicitly require these minimum Node.js versions, and will have CI testing to ensure that the minimum version is not accidentally raised again.
