We've changed the format of these release notes! We're experimenting with new release notes. See this issue for details and to give your input.

General changes

  • Web API data for selected browsers now requires version number data (#13845). For the following browsers, no null or true values remain and version numbers will be required for data added in future releases:

    • Chrome
    • Chrome for Android
    • Edge
    • Firefox
    • Internet Explorer
    • Safari
    • Safari for iOS
    • Webview Android
  • All entries using Safari 6.1, a backport release of Safari 7, have been changed to avoid unexplained discontinuities in support. Since it's no longer used in any support statements, the data for the Safari 6.1 release has been removed. See the guideline for historic Safari backport releases for more information on this change.

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 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)

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 for details and to give your input.

Notable changes

  • api.XMLHttpRequest.readyState.constants has been removed because constants, by convention, are not recorded. (#12879)

    • 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):

    • api.RTCPeerConnection.addIceCandidate.returns_promise
    • api.RTCPeerConnection.createAnswer.returns_promise
    • api.RTCPeerConnection.createOffer.returns_promise

WindowOrWorkerGlobalScope removal

To no longer expose mixins, the following features have been moved from api.WindowOrWorkerGlobalScope (or api.Window for two cases) to the global api.* namespace. The features' worker support is now indicated using worker_support sub-features. (#11518)

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, 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)

  • 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)

  • 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)

  • 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)

  • Descendant features of api.HTMLCanvasElement.getContext and api.HTMLCanvasElement.toBlob have been reorganized to follow the guideline for parameter object features. See the PR for a detailed list of features affected. (#11234)

  • The following features were lower-cased for consistency with other feature names: (#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)
    • api.TouchList.identifiedTouch (#11760)

July 29, 2021

Notable changes

  • api.MediaDevices.stereo_audio_capture was removed because it was historic, incomplete, and impractical to fix. (#11717)

July 22, 2021

Notable changes

  • api.Console was renamed to api.console to reflect the correct case of the console namespace. (#11534)

  • 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)

  • 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. See the PR for a detailed list of features affected. (#11544)

  • api.Element.attachInternals was removed, since it duplicated api.HTMLElement.attachInternals. (#11556)

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)

    Additionally, this release eliminates runtime dependencies for source distributions of this package. As of the 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 and a small allowlist for additional specifications. (#10681)

  • The mixin api.SVGFilterPrimitiveStandardAttributes has been removed and replaced by features representing its exposed interfaces. (#10646)

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, #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)

February 11, 2021

Notable changes

  • We've adopted a new data guideline for interface mixins. From v3.1.0, new data for 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)

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)
  • 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 for their insight into Node.js's history. (#7562; #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, #7492)
  • Many high-level namespaces in the package were documented and a formal Semantic Versioning policy was introduced. (#7615)
  • Data in javascript requires version number data; the javascript data no longer contains any null or true values. (#7607)
  • Addition of browsers and Removal of browsers data guidelines were adopted to document requirements to add or remove a browser or engine from package. (#7244)
  • The following features were removed as irrelevant:

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.

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 :)
