@mdn/browser-compat-data release notes (v3.x)

v3.3.14

August 5, 2021

Known issues

• In v3.3.9, the structure of features for css.properties.place-content, place-items, and place-self changed (#11214). This is an incomplete fix to the problem of undocumented namespaces appearing in places where you might otherwise expect compatibility data. The restructuring of the data is a work in progress and may change again in a future release. See #6175 for more information.

Notable changes

• Internet Explorer version "≤11" is now an accepted value, to reflect testing limitations for older versions and diminishing interest in pre-IE11 versions. (#11223)

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

  • api.Text.isElementContentWhitespace (#11859)
  • api.Document.documentURIObject (#11860)

Statistics

• 8 contributors have changed 37 files with 2,393 additions and 254 deletions in 28 commits (v3.3.13...v3.3.14)
• 13,276 total features
• 797 total contributors
• 3,473 total stargazers

v3.3.13

July 29, 2021

Notable changes

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

• A catch-all mixin feature, api.HTMLFrameSetElement.event_handlers, has been removed. Read #11675 for progress on the long-term fix of representing the WindowEventHandlers mixin's exposed interfaces. (#11459)

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

  • api.ConstrainBoolean (#11000)
  • api.ConstrainDOMString (#11000)

• 3,462 total stargazers

v3.3.12

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)

• api.ContentIndexEvent.in was renamed to api.ContentIndexEvent.id to correct a typo. (#11555)

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

  • api.HTMLSelectElement.blur (#11637)

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)

  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)

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, #7398)

v3.1.0

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)

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)
• 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)
