# jsdom Changelog ## 16.4.0 * Added a not-implemented warning if you try to use the second pseudo-element argument to `getComputedStyle()`, unless you pass a `::part` or `::slotted` pseudo-element, in which case we throw an error per the spec. (ExE-Boss) * Improved the performance of repeated access to `el.tagName`, which also indirectly improves performance of selector matching and style computation. (eps1lon) * Fixed `form.elements` to respect the `form=""` attribute, so that it can contain non-descendant form controls. (ccwebdesign) * Fixed `el.focus()` to do nothing on disconnected elements. (eps1lon) * Fixed `el.focus()` to work on SVG elements. (zjffun) * Fixed removing the currently-focused element to move focus to the `` element. (eps1lon) * Fixed `imgEl.complete` to return true for `` elements with empty or unset `src=""` attributes. (strager) * Fixed `imgEl.complete` to return true if an error occurs loading the ``, when canvas is enabled. (strager) * Fixed `imgEl.complete` to return false if the `` element's `src=""` attribute is reset. (strager) * Fixed the `valueMissing` validation check for ``. (zjffun) * Fixed `translate=""` and `draggable=""` attribute processing to use ASCII case-insensitivity, instead of Unicode case-insensitivity. (zjffun) ## 16.3.0 * Added firing of `focusin` and `focusout` when using `el.focus()` and `el.blur()`. (trueadm) * Fixed elements with the `contenteditable=""` attribute to be considered as focusable. (jamieliu386) * Fixed `window.NodeFilter` to be per-`Window`, instead of shared across all `Window`s. (ExE-Boss) * Fixed edge-case behavior involving use of objects with `handleEvent` properties as event listeners. (ExE-Boss) * Fixed a second failing image load sometimes firing a `load` event instead of an `error` event, when the `canvas` package is installed. (strager) * Fixed drawing an empty canvas into another canvas. (zjffun) ## 16.2.2 * Updated `StyleSheetList` for better spec compliance; notably it no longer inherits from `Array.prototype`. (ExE-Boss) * Fixed `requestAnimationFrame()` from preventing process exit. This likely regressed in v16.1.0. * Fixed `setTimeout()` to no longer leak the closures passed in to it. This likely regressed in v16.1.0. (AviVahl) * Fixed infinite recursion that could occur when calling `click()` on a `` element, or one of its descendants. * Fixed `getComputedStyle()` to consider inline `style=""` attributes. (eps1lon) * Fixed several issues with ``'s `stepUp()` and `stepDown()` functions to be properly decimal-based, instead of floating point-based. * Fixed various issues where updating `selectEl.value` would not invalidate properties such as `selectEl.selectedOptions`. (ExE-Boss) * Fixed ``'s `src` property, and ``/``'s `cite` property, to properly reflect as URLs. * Fixed `window.addEventLister`, `window.removeEventListener`, and `window.dispatchEvent` to properly be inherited from `EventTarget`, instead of being distinct functions. (ExE-Boss) * Fixed errors that would occur if attempting to use a DOM object, such as a custom element, as an argument to `addEventListener`. * Fixed errors that would occur when closing a window with outstanding requests to `data:` URLs. * Fixed sporadic issues with the value of `` that could occur in some time zones and for some times. * Fixed `document.implementation.createDocument()` to return an `XMLDocument`, instead of a `Document`. (ExE-Boss) * Fixed running jsdom in a browser to detect globals more reliably. (ExE-Boss) ## 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 issues when trying to use `Attr` as a `Node`, e.g. by checking its `baseURI` property or calling `attr.cloneNode()`. * Fixed a memory leak during parsing that was introduced in v14.0.0. * Fixed edge cases in number/string conversion used for certain element properties that reflected integer attributes. ## 16.1.0 * Added `console.timeLog()`. * Changed `Attr` to extend `Node`, to align with specifications. (ExE-Boss) * Changed `
