Sourced from jsdom's releases.

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.

Since reverting to nwsapi causes several functionality regressions, e.g. removing :has() support, we've decided to make this a major version.

Additionally:

• Small fixes to edge-case behavior of the following properties: input.maxLength, input.minLength, input.size, progress.max, tableCell.colSpan, tableCell.rowSpan, tableCol.span, textArea.cols, textArea.maxLength, textArea.minLength, textArea.rows.

Version 23.2.0

This release switches our CSS selector engine from nwsapi to @asamuzakjp/dom-selector. The new engine is more actively maintained, and supports many new selectors: see the package's documentation for the full list. It also works better with shadow trees.

There is a potential of a performance regression due to this change. In our stress test benchmark, which runs most of these 273 selectors against this 128 KiB document, the new engine completes the benchmark only 0.25x as fast. However, we're hopeful that in more moderate usage this will not be a significant issue. Any help speeding up @asamuzakjp/dom-selector is appreciated, and feel free to open an issue if this has had a significant impact on your project.

Version 23.1.0

• Added an initial implementation of ElementInternals, including the shadowRoot getter and the string-valued ARIA properties. (zjffun)
• Added the string-valued ARIA attribute-reflecting properties to Element.
• Fixed history.pushState() and history.replaceState() to follow the latest specification, notably with regards to how they handle empty string inputs and what new URLs are possible.
• Fixed the input.valueAsANumber setter to handle NaN correctly. (alexandertrefz)
• Updated various dependencies, including cssstyle which contains several bug fixes.

Version 23.0.1

• Fixed the incorrect canvas peer dependency introduced in v23.0.0.

Version 23.0.0

• Node.js v18 is now the minimum supported version.
• Updated various dependencies, including whatwg-url which integrates various additions to the URL and URLSearchParams objects.
