## 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 ``. * Fixed `selectEl.value` when no `` 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` 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 `` 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 `` and `` elements whose `href=""` points to a `javascript:` URL or fragment. * Added the `
