## 16.2.1
* Updated `saxes`, to bring in some BOM-related fixes.
* Updated Acorn-related packages to squelch `npm audit` warnings.
## 16.2.0
* Added support for custom elements! Congratulations and thanks to [@pmdartus](https://github.com/jsdom/jsdom/commits?author=pmdartus) for making this happen, after ten months of hard work and lots of effort poured into the complex architectural prerequisites in jsdom and supporting packages.

* Fixed some selection-related issues when manipulating the value of `<input>`s and `<textarea>`s. (Matthew-Goldberg)
* Fixed various issues with `setTimeout()`, `setInterval()`, and `requestAnimationFrame()`, particularly around window closing and recursive calls.
## 16.0.1
* Fixed Node v10 and v11 support when `runScripts` was set.
* Fixed the behavior when changing an `<input>`'s `type=""` attribute.
* Fixed input validation behavior for `<input type="range">` when `max=""` is less than `min=""`.
## 16.0.0
For this release we'd like to welcome [@pmdartus](https://github.com/jsdom/jsdom/commits?author=pmdartus) to the core team. Among other work, he's driven the heroic effort of constructor prototype and reform in jsdom and its dependencies over the last few months, to allow us to move away from shared constructors and prototypes, and set the groundwork for custom elements support ([coming soon](https://github.com/jsdom/jsdom/pull/2548)!).
Breaking changes:
* Node v10 is now the minimum supported version.
* The `dom.runVMScript()` API has been replaced with the more general `dom.getInternalVMContext()` API.
* Each jsdom `Window` now creates new instances of all the web platform globals. That is, our old [shared constructor and prototypes](https://github.com/jsdom/jsdom/blob/35894a6703ed1f4de98942780bd99244ac27f600/README.md#shared-constructors-and-prototypes) caveat is no longer in play.
* Each jsdom `Window` now exposes all JavaScript-spec-defined globals uniformly. When `runScripts` is disabled, it exposes them as aliases of the ones from the outer Node.js environment. Whereas when `runScripts` is enabled, it exposes fresh copies of each global from the new scripting environment. (Previously, a few typed array classes would always be aliased, and with `runScripts` disabled, the other classes would not be exposed at all.)
Other changes:
* Added the `AbstractRange`, `Range`, `StaticRange`, `Selection`, and `window.getSelection()` APIs.
* Added working constructors for `Comment`, `Text`, and `DocumentFragment`.
* Added `valueAsDate`, `valueAsNumber`, `stepUp()` and `stepDown()` to `<input>` elements. (kraynel)
* Added `window.origin`.
* Removed `document.origin`.
* Fixed `<template>` to work correctly inside XML documents.
* Fixed some bugs which would cause jsdom to choose the wrong character encoding because it was failing to detect `<meta charset>` or `<meta http-equiv="charset">` elements.
* Fixed `input.type` to default to `"text"`. (connormeredith)
* Fixed incorrect validation errors for `<input>` with fractional values for their `step=""` attribute. (kontomondo)
* Fixed incorrect validation errors on readonly `<input>` elements.
* Fixed `<input type="email" multiple pattern="...">` validation.
* Fixed `fileReader.readAsDataURL()` to always base64-encode the result. (ytetsuro)
* Fixed inserting `<img>` elements into documents without a browsing context to no longer crash when the `canvas` package is installed.
* Fixed a memory leak when using `window.setTimeout()` or `window.setInterval()`.
* Improved the performance of `getComputedStyle()`. (eps1lon)
## 15.2.1
* Fixed `JSDOM.fromURL()` handling of URLs with hashes in them, to no longer send the hash to the server and append an extra copy of it when constructing the `Document`. (rchl)
* Fixed focusing an already-focused element to correctly do nothing, instead of firing additional `focus` events. (eps1lon)
* Fixed typo in the not-implemented message for `mediaElement.addTextTrack()`. (mtsmfm)
* Upgraded `nwsapi` minimum version to 2.2.0, which fixes issues with `::-webkit-` prefixed pseudo-elements and namespaced attribute selectors.
## 15.2.0
* Added basic style inheritance in `getComputedStyle()` for the `'visibility'` property. This sets the foundation for further work on inheritance, cascading, and specificity. (eps1lon)
* Added `shadowRoot.activeElement`.
* Added `readystatechange` events during document loading.
* Added a stub for `form.requestSubmit()`, to match our existing stub for `form.submit()`.
* Changed `el.tabIndex`'s default value, when no `tabindex=""` attribute was set, to reflect the updated specification.
* Changed the exception thrown by `el.attachShadow()` on something that's already a shadow host, to reflect the updated specification.
* Fixed the validation logic for `<input type="range">`.
* Fixed `selectEl.value` when no `<option>` is selected to return the empty string, instead of the value of the first option. (tgohn)
* Fixed various correctness issues with `new FormData(formElement)`. (brendo)
* Fixed error messages when parsing XML to include the filename, instead of using `"undefined"`. (papandreou)
* Fixed the logic for reflected properties to not be affected by overwriting of `el.getAttributeNS()` or `el.setAttributeNS()`.
* Set `canvas` as an optional ``peerDependency`, which apparently helps with Yarn PnP support.
## 15.1.1
* Moved the `nonce` property from `HTMLScriptElement` and `HTMLStyleElement` to `HTMLElement`. Note that it is still just a simple reflection of the attribute, and has not been updated for the rest of the changes in [whatwg/html#2373](https://github.com/whatwg/html/pull/2373).
* Fixed the `style` and `on<event>` properties to properly track their related attributes for SVG elements. (kbruneel)
* Fixed `XMLHttpRequest` merging preflight and response headers. (thiagohirata)
* Fixed `XMLHttpRequest` reserializing `content-type` request headers unnecessarily. See [whatwg/mimesniff#84](https://github.com/whatwg/mimesniff/issues/84) for more details. (thiagohirata)
* Fixed `element.tagName` to be the ASCII uppercase of the element's qualified name, instead of the Unicode uppercase.
## 15.1.0
* Added the `Headers` class from the Fetch standard.
* Added the `element.translate` getter and setter.
* Fixed synchronous `XMLHttpRequest` on the newly-released Node.js v12.
* Fixed `form.elements` to exclude `<input type="image">` elements.
* Fixed event path iteration in shadow DOM cases, following spec fixes at [whatwg/dom#686](https://github.com/whatwg/dom/pull/686) and [whatwg/dom#750](https://github.com/whatwg/dom/pull/750).
* Fixed `pattern=""` form control validation to apply the given regular expression to the whole string. (kontomondo)
## 15.0.0
Several potentially-breaking changes, each of them fairly unlikely to actually break anything:
* `JSDOM.fromFile()` now treats `.xht` files as `application/xhtml+xml`, the same as it does for `.xhtml` and `.xml`. Previously, it would treat them as `text/html`.
* If the `JSDOM` constructor's `contentType` option has a `charset` parameter, and the first argument to the constructor is a binary data type (e.g. `Buffer` or `ArrayBuffer`), then the `charset` will override any sniffed encoding in the same way as a `Content-Type` header would in browser scenarios. Previously, the `charset` parameter was ignored.
* When using the `Blob` or `File` constructor with the `endings: "native"` option, jsdom will now convert line endings to `\n` on all operating systems, for consistency. Previously, on Windows, it would convert line endings to `\r\n`.
## 14.1.0
* Added activation behavior for `<a>` and `<area>` elements whose `href=""` points to a `javascript:` URL or fragment.

For this release we'd like to welcome [@Zirro](https://github.com/jsdom/jsdom/commits?author=Zirro) to the core team; his contributions over the course of this year have enhanced jsdom immensely.
* Added a rudimentary set of SVG element classes, namely `SVGElement`, `SVGGraphicsElement`, `SVGSVGElement`, `SVGTests`, `SVGAnimatedString`, `SVGNumber`, and `SVGStringList`. The main impact here is that SVG elements are now instances of `SVGElement`, instead of being simply `Element` (as they were in v11.3.0) or `HTMLUnknownElement` (as they were in v11.2.0 and previously). The only concrete subclass that is implemented is `SVGSVGElement`, for `<svg>` itself; other tags will not map to their correct classes, because those classes are not yet implemented.
* Added the new `pretendToBeVisual` option, which controls the presence of the new `requestAnimationFrame()` and `cancelAnimationFrame()` methods, and the new values of `document.hidden`/`document.visibilityState`.

However, recent performance investigations revealed that mutation events were the major bottleneck in most jsdom operations; tools like [ecmarkup](https://github.com/bterlson/ecmarkup) which make heavy use of jsdom had their running time halved by removing mutation events, which add serious overhead to every DOM mutation. As such, we are doing a major release with them removed, so that jsdom users can benefit from this massive performance gain.

- `window.onerror` (or `window.addEventListener("error", ...)`) now work, and will catch all script errors, similar to in browsers. This also introduces the `ErrorEvent` class, incidentally.

Starting with the 1.0.0 release, we will be following semantic versioning, so that you can depend on stability within major version ranges. But we still have [a few more issues](https://github.com/tmpvar/jsdom/issues?q=is%3Aopen+is%3Aissue+milestone%3A1.0) before we can get there, so I don't want to do 1.0.0 quite yet.

### Major changes
* jsdom now can be browserified into a bundle that works in web workers! This is highly experimental, but also highly exciting! (lawnsea)
* An overhaul of the [initialization lifecycle](https://github.com/tmpvar/jsdom#initialization-lifecycle), to bring more control and address common use cases. (Sebmaster)

* The excellent [parse5](https://npmjs.org/package/parse5) HTML parser is now the default parser, fixing many parsing bugs and giving us full, official-test-suite-passing HTML parsing support. This especially impacts documents that didn't include optional tags like `<html>`, `<head>`, or `<body>` in their source. We also use parse5 for serialization, fixing many bugs there. (Sebmaster)
* As part of the new parser story, we are not supporting XML for now. It might work if you switch to a different parser (e.g. htmlparser2), but in the end, HTML and XML are very different, and we are not attempting to be an XML DOM. That said, we eventually want to support XML to the same extent browsers do (i.e., support XHTML and SVG, with an appropriate MIME type switch); this is being planned in [#820](https://github.com/tmpvar/jsdom/issues/820).
