Sourced from jsdom's releases.

Version 26.1.0

• Added at least partial support for various SVG elements and their classes: <defs> (SVGDefsElement), <desc> (SVGDescElement), <g> (SVGGElement), <metadata> (SVGMetadataElement), <switch> (SVGSwitchElement), and <symbol> (SVGSymbolElement).
• Added SVGAnimatedPreserveAspectRatio and SVGAnimatedRect, including support in the reflection layer.
• Added the SVGSVGElement createSVGRect() method, and the SVGRect type (which is distinct from DOMRect.)
• Added indexed property support to HTMLFormElement.
• Updated the SVGElement viewportElement() method to correctly establish the viewport based on ancestor elements.
• Removed the now-bloated form-data dependency in favor of our own smaller implementation of multipart/form-data serialization. No functional changes are expected.
• Various performance improvements, caches, microoptimizations, and deferred object creation.

Version 26.0.0

Breaking change: canvas peer dependency requirement has been upgraded from v2 to v3. (sebastianwachter)

Other changes:

• Added AbortSignal.any(). (jdbevan)
• Added initial support for form-associated custom elements, in particular making them labelable and supporting the ElementInternals labels property. The form-associated callbacks are not yet supported. (hesxenon)
• Updated whatwg-url, adding support for URL.parse().
• Updated cssstyle and rrweb-cssom, to improve CSS parsing capabilities.
• Updated nwsapi, improving CSS selector matching.
• Updated parse5, fixing a bug around <noframes> elements and HTML entity decoding.
• Fixed JSDOM.fromURL() to properly reject the returned promise if the server redirects to an invalid URL, instead of causing an uncaught exception.

Version 25.0.1

• Updated dependencies, notably tough-cookie, which no longer prints a deprecation warning.

Version 25.0.0

This major release changes the prototype of a jsdom's EventTarget.prototype to point to the Object.prototype inside the jsdom, instead of pointing to the Node.js Object.prototype. Thus, the prototype chain of Window stays entirely within the jsdom, never crossing over into the Node.js realm.

This only occurs when runScripts is set to non-default values of "dangerously" or "outside-only", as with the default value, there is no separate Object.prototype inside the jsdom.

This will likely not impact many programs, but could cause some changes in instanceof behavior, and so out of an abundance of caution, we're releasing it as a new major version.

Version 24.1.3

• Fixed calls to postMessage() that were done as a bare property (i.e., postMessage() instead of window.postMessage()).

Version 24.1.2

• Fixed an issue with the in operator applied to EventTarget methods, e.g. 'addEventListener' in window, which only appeared in Node.js ≥22.5.0. (legendecas)
• Fixed the events fired by blur(): it no longer fires focus and focusin on the Document, and blur and focusout no longer have their relatedTarget property set. (asamuzaK)

Version 24.1.1

• Fixed selection methods to trigger the selectionchange event on the Document object. (piotr-oles)

Version 24.1.0

• Added the getSetCookie() method to the Headers class. (ushiboy)
• Fixed the creation and parsing of elements with names from Object.prototype, like "constructor" or "toString".
• Updated rweb-cssom, which can now parse additional CSS constructs.

Version 24.0.0

This release reverts our selector engine back to nwsapi. As discussed in #3659, the performance regressions from @asamuzakjp/dom-selector turned out to be higher than anticipated. In the future, we can revisit @asamuzakjp/dom-selector after it reaches nwsapi's performance on the two real-world benchmarks provided by the community.

Changes since 26.1.0

• Node.js v20 is now the minimum supported version.
• 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.)
• Added customElements.getName(). (mash-graz)
• Updated the virtual console:
  • "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.
• Switched our CSS selector engine from nwsapi to @asamuzakjp/dom-selector, closing over 20 selector-related bugs.
• 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)
• Fixed CSS display style resolution. (asamuzaK)

Changes since 27.0.0-beta.3

• Upgraded cssstyle, which brings along various CSS parsing fixes.

27.0.0-beta.3

• 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)

27.0.0-beta.2

Significantly improved specification conformance for the Window object, including named properties and changing various data properties to accessor properties. This is not likely to be breaking, but since it's a complex change to such a core object, we're happy to do another beta testing release with this included before graduating the v27 line to stable.

Additionally, updated cssstyle to v4.4.0, which brings along various conformance fixes to the CSSStyleDeclaration object and its properties.

27.0.0-beta.1
