Release Notes

v29.0.1

Compare Source

v29.0.0

Compare Source

Breaking changes:

  • 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 cssKeyframeRule.keyText getter/setter validation.
  • Added cssStyleRule.selectorText setter validation: invalid selectors are now rejected.
  • Added styleSheet.ownerNode, styleSheet.href, and styleSheet.title.
  • Added bad port blocking per the fetch specification, preventing fetches to commonly-abused ports.
  • Improved Document initialization performance by lazily initializing the CSS selector engine, avoiding ~0.5 ms of overhead per Document. (thypon)
  • Fixed a memory leak when stylesheets were removed from the document.
  • Fixed CSSStyleDeclaration modifications to properly trigger custom element reactions.
  • Fixed nested @media rule parsing.
  • Fixed CSSStyleSheet's "disallow modification" flag not being checked in all mutation methods.
  • Fixed XMLHttpRequest's response getter returning parsed JSON during the LOADING state instead of null.
  • Fixed getComputedStyle() crashing in XHTML documents when stylesheets contained at-rules such as @page or @font-face.
  • Fixed a potential hang in synchronous XMLHttpRequest caused by a race condition with the worker thread's idle timeout.

v28.1.0

Compare Source

  • 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.

v28.0.0

Compare Source

  • 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.
  • Fixed many small issues in XMLHttpRequest.

v27.4.0

Compare Source

  • Added TextEncoder and TextDecoder.
  • Improved decoding of HTML bytes by using the new @exodus/bytes package; it is now much more correct. (ChALkeR)
  • Improved decoding of XML bytes to use UTF-8 more often, instead of sniffing for <meta charset> or using the parent frame's encoding.
  • Fixed a memory leak when Ranges were used and then the elements referred to by those ranges were removed.

v27.3.0

Compare Source

  • Improved CSS parsing and CSSOM object APIs via updates to @acemir/cssom. (acemir)

v27.2.0

Compare Source

  • Added CSSGroupingRule, CSSNestedDeclarations, CSSConditionRule, CSSContainerRule, CSSScopeRule, CSSSupportsRule, CSSLayerBlockRule, and CSSLayerStatementRule to jsdom Windows. (acemir)
  • Improved CSS parsing and CSSOM object APIs via updates to @acemir/cssom. (acemir)
  • Fixed @import-ed stylesheets to be properly exposed to CSSOM, and not to overwrite the sheet created from the <link> or <style> element. (acemir)

v27.1.0

Compare Source

  • 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.

v27.0.1

Compare Source

  • 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)
