# Release notes

## [v4.0.13](https://github.com/mdn/browser-compat-data/releases/tag/v4.0.13)

December 1, 2021

**We've changed the format of these release notes!** We're experimenting with new release notes. See [this issue](https://github.com/mdn/browser-compat-data/issues/13229) for details and to [give your input](https://github.com/mdn/browser-compat-data/issues/13229).

### Data guideline changes

A data guideline has been adopted to represent DOM events by a single `eventname_event` feature on each event's target interface, instead of separate features for the event name and `on`-handler properties. For example, `api.Element.focus_event` and `api.Element.onfocus` would be consolidated into `api.Element.focus_event` only. Read [the complete guideline](https://github.com/mdn/browser-compat-data/blob/main/docs/data-guidelines.md#dom-events-eventname_event) for details.

This consolidation will be completed over several `@mdn/browser-compat-data` releases. Review the release notes for a complete list of features added or removed. ([#13595](https://github.com/mdn/browser-compat-data/pull/13595))

## [v4.0.11](https://github.com/mdn/browser-compat-data/releases/tag/v4.0.11)

November 16, 2021

**Last call: do you read these release notes?** We're considering making changes to them and want to hear from you before we do that. See [this issue](https://github.com/mdn/browser-compat-data/issues/13229) for details and to [give your input](https://github.com/mdn/browser-compat-data/issues/13229).

### Notable changes

- `api.XMLHttpRequest.readyState.constants` has been removed because constants, [by convention](https://github.com/mdn/browser-compat-data/blob/main/docs/data-guidelines.md#constants), are not recorded. ([#12879](https://github.com/mdn/browser-compat-data/pull/12879))

- The following non-existent, long-removed, or otherwise irrelevant features have been removed:

  - `api.MediaStreamAudioSourceOptions` ([#13523](https://github.com/mdn/browser-compat-data/pull/13523))
  - `api.PhotoCapabilities` ([#13479](https://github.com/mdn/browser-compat-data/pull/13479))

This is an incomplete fix to the problem of undocumented namespaces appearing in places where you might otherwise expect compatability data. The restructuring of the data is a work in progress and may change again in a future release. See [#6175](https://github.com/mdn/browser-compat-data/issues/6175) for more information.

October 12, 2021

### Notable changes

- The dictionary `api.ScrollToOptions` has been removed and replaced by parameter features on methods that consume the dictionary. ([#12490](https://github.com/mdn/browser-compat-data/pull/12490))

- To no longer expose global mixins, `api.Window.performance` has been moved to `api.performance`. ([#12462](https://github.com/mdn/browser-compat-data/pull/12462))

- To correct capitalization, the features `api.TextTrackList.addTrack_event` and `api.TextTrackList.removeTrack_event` were renamed to `api.TextTrackList.addtrack_event` and `api.TextTrackList.removetrack_event` respectively. ([#12723](https://github.com/mdn/browser-compat-data/pull/12723))

## [v4.0.5](https://github.com/mdn/browser-compat-data/releases/tag/v4.0.5)

September 23, 2021

### Notable changes

- The feature-naming convention `returns_promise` has been adopted for features that capture some but not all browsers' APIs returning a `Promise`. The [new data guideline](https://github.com/mdn/browser-compat-data/blob/main/docs/data-guidelines.md#methods-returning-promises-returns_promise) brings consistency to competing styles used throughout the API data.

  The following features have been renamed to `returns_promise` ([#11630](https://github.com/mdn/browser-compat-data/pull/11630)):

  - `api.BaseAudioContext.decodeAudioData.promise_syntax`
  - `api.Document.exitFullscreen.returns_a_promise`
  - `api.Element.requestFullscreen.returns_a_promise`
  - `api.OfflineAudioContext.startRendering.Promise_based_startRendering`

  The feature `api.RTCPeerConnection.getStats.with_callbacks` was removed and the data for several `RTCPeerConnection` methods expanded with `returns_promise` data. The following features have been added ([#12300](https://github.com/mdn/browser-compat-data/pull/12300)):

  - `api.RTCPeerConnection.addIceCandidate.returns_promise`
  - `api.RTCPeerConnection.createAnswer.returns_promise`
  - `api.RTCPeerConnection.createOffer.returns_promise`
  - `api.RTCPeerConnection.getStats.returns_promise`
  - `api.RTCPeerConnection.setLocalDescription.returns_promise`
  - `api.RTCPeerConnection.setRemoteDescription.returns_promise`

- The following non-existent, long-removed, or otherwise irrelevant features have been removed:

  - `api.CryptoKeyPair` ([#12346](https://github.com/mdn/browser-compat-data/pull/12346))
  - `api.MediaStream.ended` ([#12454](https://github.com/mdn/browser-compat-data/pull/12454))
  - `api.MediaStream.label` ([#12455](https://github.com/mdn/browser-compat-data/pull/12455))
  - `api.SVGZoomAndPan` ([#12518](https://github.com/mdn/browser-compat-data/pull/12518))
  - `api.Window.maximize` ([#12552](https://github.com/mdn/browser-compat-data/pull/12552))
  - `api.Window.minimize` ([#12552](https://github.com/mdn/browser-compat-data/pull/12552))
  - `api.XMLSerializer.serializeToStream` ([#12417](https://github.com/mdn/browser-compat-data/pull/12417))

### Known issues

- In [v3.3.9](https://github.com/mdn/browser-compat-data/releases/tag/v3.3.9), the structure of features for `css.properties.place-content`, `place-items`, and `place-self` changed ([#11214](https://github.com/mdn/browser-compat-data/pull/11214)).

## [v4.0.0](https://github.com/mdn/browser-compat-data/releases/tag/v4.0.0)

August 19, 2021

Version 4.0.0 makes some potentially-breaking changes to improve the flexibility and quality of the data. Higlights include:

- The schema now supports a `"preview"` version value for in-development browser releases, such as Safari Technology Preview, Chrome Canary, and Firefox Nightly.
- Deno, the JavaScript and TypeScript runtime, has been added as a new engine.
- All XPath (`xpath`) and XSLT (`xslt`) features have been removed because the data was incomplete and unmaintained.
- The schema for browser release data now supports the optional `accepts_flags` boolean hint.

### Notable changes

- [Deno](https://deno.land/), the JavaScript and TypeScript runtime, has been added as a new engine. Deno data is included for JavaScript and some Web APIs, much like Node.js data. ([#10753](https://github.com/mdn/browser-compat-data/pull/10753))

- The XPath (`xpath`) and XSLT (`xslt`) features have been removed. These features poorly covered their subjects and were unmaintained. Rather than purport to have such data, we removed it.

  We're not ruling out the return of XPath and XSLT data in the future. But for now, in the absence of an intentional effort to create and maintain that data, we thought it best to remove the faulty data. ([#9830](https://github.com/mdn/browser-compat-data/pull/9830))

- The schema now supports a special version value `"preview"` for in-development versions of browsers, such as Safari Technology Preview, Chrome Canary, and Firefox Nightly. Additionally, browser data now supports a `preview_name` property for supplying a corresponding name for the preview browser.

  These additions to the schema should help represent features gated to development versions, which were previously misrepresented with notes, `false` values, or inaccurate version numbers. ([#10334](https://github.com/mdn/browser-compat-data/pull/10334))

- The schema for browser release data now supports the optional `accepts_flags` boolean hint, which indicates whether a browser (or individual release) should contain `flags` data. Presently, this is a hint for data contributors or tools. The value of `accepts_flags` doesn't (yet) make any guarantees about the contents of feature data. ([#11286](https://github.com/mdn/browser-compat-data/pull/11286))

- Descendant features of `api.HTMLCanvasElement.getContext` and `api.HTMLCanvasElement.toBlob` have been reorganized to follow [the guideline for parameter object features](https://github.com/mdn/browser-compat-data/blob/main/docs/data-guidelines.md#parameters-and-parameter-object-features). See [the PR for a detailed list of features affected](https://github.com/mdn/browser-compat-data/pull/11234#issuecomment-900265901). ([#11234](https://github.com/mdn/browser-compat-data/pull/11234))

- The following features were lower-cased for consistency with other feature names: ([#11961](https://github.com/mdn/browser-compat-data/pull/11961))

  - `api.CanvasRenderingContext2D.drawImage.Smoothing_downscaling` (now `smoothing_downscaling`)
  - `api.OfflineAudioContext.OfflineAudioContext.Parameters_accepted_in_an_object` (now `parameters_accepted_in_an_object`)

- The following non-existent, long-removed, or otherwise irrelevant features have been removed:

  - `api.AnimationEvent.initAnimationEvent` ([#12059](https://github.com/mdn/browser-compat-data/pull/12059))
  - `api.TouchList.identifiedTouch` ([#11760](https://github.com/mdn/browser-compat-data/pull/11760))

- Safari for iOS 5.1 and 3.1 data was corrected to version 5.0 and 3.0, respectively, since these browsers were found to support the same features. Since no data now uses the version 5.1 and 3.1 values, they were dropped from the release data. ([#11175](https://github.com/mdn/browser-compat-data/pull/11175))

- The descendant features of `javascript.builtins.Intl.DateTimeFormat.DateTimeFormat` (the `Intl.DateTimeFormat()` constructor's parameters) have been reorganized to follow [the guideline for parameter object features](https://github.com/mdn/browser-compat-data/blob/main/docs/data-guidelines.md#parameters-and-parameter-object-features). See [the PR for a detailed list of features affected](https://github.com/mdn/browser-compat-data/pull/11544#issuecomment-884885596). ([#11544](https://github.com/mdn/browser-compat-data/pull/11544))

- `api.Element.attachInternals` was removed, since it duplicated `api.HTMLElement.attachInternals`. ([#11556](https://github.com/mdn/browser-compat-data/pull/11556))

- `api.ContentIndexEvent.in` was renamed to `api.ContentIndexEvent.id` to correct a typo. ([#11555](https://github.com/mdn/browser-compat-data/pull/11555))

- The following non-existent, long-removed, or otherwise irrelevant features have been removed:

  - `api.HTMLSelectElement.blur` ([#11637](https://github.com/mdn/browser-compat-data/pull/11637))
  - `api.HTMLSelectElement.focus` ([#11637](https://github.com/mdn/browser-compat-data/pull/11637))
  - `api.KeyboardEvent.KeyboardEvent.code_and_key_in_init` ([#11530](https://github.com/mdn/browser-compat-data/pull/11530))
  - `api.WorkerGlobalScope.close_event` ([#11557](https://github.com/mdn/browser-compat-data/pull/11557))
  - `api.WorkerGlobalScope.close` ([#11557](https://github.com/mdn/browser-compat-data/pull/11557))
  - `api.WorkerGlobalScope.onclose` ([#11557](https://github.com/mdn/browser-compat-data/pull/11557))
  - `api.XREnvironmentBlendMode` ([#11551](https://github.com/mdn/browser-compat-data/pull/11551))
  - `api.XREye` ([#11636](https://github.com/mdn/browser-compat-data/pull/11636))
  - `api.XRFrameRequestCallback` ([#11633](https://github.com/mdn/browser-compat-data/pull/11633))
  - `api.XRWebGLLayerInit` ([#11661](https://github.com/mdn/browser-compat-data/pull/11661))

## [v3.3.6](https://github.com/mdn/browser-compat-data/releases/tag/v3.3.6)

June 4, 2021

### Notable changes

- The `extend` dependency has been removed and replaced by a more narrowly scoped function, which prevents two (or more) data files from erroneously setting data for the same feature. ([#9821](https://github.com/mdn/browser-compat-data/pull/9821))

  Additionally, this release eliminates runtime dependencies for source distributions of this package. As of the [v3.3.0](https://github.com/mdn/browser-compat-data/releases/tag/v3.3.0) release, the `@mdn/browser-compat-data` package published on npm has zero dependencies; this release extends that benefit to installing the package from the repository source (such as from GitHub's releases assets).

- Specification URLs (`spec_url` values) are now validated against [`w3c/browser-specs`](https://github.com/w3c/browser-specs) and a small allowlist for additional specifications. ([#10681](https://github.com/mdn/browser-compat-data/pull/10681))

- The mixin `api.SVGFilterPrimitiveStandardAttributes` has been removed and replaced by features representing its exposed interfaces. ([#10646](https://github.com/mdn/browser-compat-data/pull/10646))

## [v3.3.0](https://github.com/mdn/browser-compat-data/releases/tag/v3.3.0)

April 15, 2021

### Notable changes

- `@mdn/browser-compat-data` is now smaller, faster to load, and has zero dependencies.

  The data is now bundled into a single JSON file at publishing time, instead of loading many JSON files at runtime. This reduces the size of the package and shortens loading times.

  These changes also eliminate dependencies. There are zero runtime package dependencies and Node.js ≥10.0.0 is no longer required. This version of the package has been shown to load in many end-of-life versions of Node.js.

  ([#7374](https://github.com/mdn/browser-compat-data/issues/7374), [#7398](https://github.com/mdn/browser-compat-data/pull/7398))

- `css.selectors.not_match_link` feature has been removed. The data is now correctly represented as `css.selectors.any-link.not_match_link` and `css.selectors.link.not_match_link`. ([#9842](https://github.com/mdn/browser-compat-data/pull/9842))

## [v3.2.0](https://github.com/mdn/browser-compat-data/releases/tag/v3.2.0)

March 11, 2021

### Notable changes

- [Support statement objects](https://github.com/mdn/browser-compat-data/blob/v3.2.0/schemas/compat-data-schema.md#the-support_statement-object) may no longer use `false` or `null` values for `version_removed`. Values for `version_removed` are now required to be real version numbers or `true` (removed in some unknown version). This change to the schema codifies a widely-followed practice within existing compatability data. ([#9015](https://github.com/mdn/browser-compat-data/pull/9015))

- The following features were renamed:

  - `api.SVGFECompositeElement.in` is now `api.SVGFECompositeElement.in1`, fixing a misidentified attribute (again). ([#9074](https://github.com/mdn/browser-compat-data/pull/9074), [#9343](https://github.com/mdn/browser-compat-data/pull/9343))
  - `api.SVGTests.hasextension` is now `api.SVGTests.hasExtension`, fixing incorrect capitalization. ([#9387](https://github.com/mdn/browser-compat-data/pull/9387))
  - `api.SVGViewElement.viewtarget` is now `api.SVGViewElement.viewTarget`, fixing incorrect capitalization. ([#9387](https://github.com/mdn/browser-compat-data/pull/9387))

## [v3.1.0](https://github.com/mdn/browser-compat-data/releases/tag/v3.1.0)

February 11, 2021

**Notable changes**

- We've adopted [a new data guideline for interface mixins](docs/data-guidelines.md#mixins). From v3.1.0, new data for [interface mixins](https://webidl.spec.whatwg.org/#idl-interface-mixins) will be represented as subfeatures of their exposed interfaces, instead of fictitious mixin interfaces.

  For example, `HTMLHyperlinkElementUtils` attributes are now represented on `HTMLAnchorElement` and `HTMLAreaElement` directly.

  Existing interface mixins data will be replaced as part of our regular release process. The release notes will describe specific changes as they happen. ([#9016](https://github.com/mdn/browser-compat-data/pull/9016))

- The following mixin features have been migrated to their exposed interfaces ([#8933](https://github.com/mdn/browser-compat-data/pull/8933), [#9046](https://github.com/mdn/browser-compat-data/pull/9046), [#9048](https://github.com/mdn/browser-compat-data/pull/9048)):

## [v3.0.0](https://github.com/mdn/browser-compat-data/releases/tag/v3.0.0)

December 10, 2020

Version 3.0.0 makes some potentially-breaking changes to improve the consistency and quality of the data. Highlights:

- UC and QQ browsers were removed.
- A public API, in addition to the schema, was formalized for better adherence to Semantic Versioning.
- Node.js's data was made more consistent with this project's other engines. Node.js data now starts at 0.10.0, as if it were Node.js's first major release, and Node.js version strings consistently use the full version value (for example, `0.12.0` instead of `0.12`).

Review the changes below for details.

**Notable changes**

- **(Breaking)** UC and QQ browsers were removed from the schema and support data, due to limited coverage and contribution activity. ([#7240](https://github.com/mdn/browser-compat-data/issues/7240))
- Node.js data with releases before `0.10.0` were increased to that version, as if this were the first major, stable release (though the true story is rather more complex). Special thanks to the [Node.js Release Working Group](https://github.com/nodejs/Release) for their insight into Node.js's history. ([#7562](https://github.com/mdn/browser-compat-data/issues/7562); [#6861](https://github.com/mdn/browser-compat-data/issues/6861))
- Node.js versions `0.10` and `0.12` were replaced by their full SemVer values, `0.10.0` and `0.12.0`, respectively. ([#7491](https://github.com/mdn/browser-compat-data/issues/7491), [#7492](https://github.com/mdn/browser-compat-data/issues/7492))
- Many high-level namespaces in the package were [documented](https://github.com/mdn/browser-compat-data#package-contents) and [a formal Semantic Versioning policy was introduced](https://github.com/mdn/browser-compat-data#semantic-versioning-policy). ([#7615](https://github.com/mdn/browser-compat-data/issues/7615))
- Data in `javascript` requires version number data; the `javascript` data no longer contains any `null` or `true` values. ([#7607](https://github.com/mdn/browser-compat-data/issues/7607))
- [_Addition of browsers_](docs/data-guidelines.md#addition-of-browsers) and [_Removal of browsers_](docs/data-guidelines.md#removal-of-browsers) data guidelines were adopted to document requirements to add or remove a browser or engine from package. ([#7244](https://github.com/mdn/browser-compat-data/issues/7244))

## [v1.0.0](https://github.com/mdn/browser-compat-data/releases/tag/v1.0.0)

November 21, 2019

The mdn-browser-compat-data 1.0.0 release is a non-breaking release! It is the 100th release of fresh compat data brought to you by the MDN team at Mozilla.

From now on: we're guaranteeing data structure stability and any changes to how the data is exposed will be communicated using minor and major version bumps. Compatibility data will still be continuously updated on a weekly basis and the patch version will be used if data-only updates happened. So, you can expect a 1.0.1 release next week.

### Notable changes

**Next week (on 21st November 2019), we will release version 1.0.0 (instead of 0.0.100). Please make sure your package.json semver query takes this into account! (see also npm semver calculator at https://semver.npmjs.com/)**

There are no breaking changes in 1.0.0. It is just that we should finally use semver correctly and call it a 1.0.0 :)
