Project: 
Introduced in branch: 
8.8.x
Introduced in version: 
8.8.0-alpha1
Description: 

Starting from Drupal 8.8.0, Drupal core supports the following browsers:

  • The latest release of each of the latest two major versions of:
    • Desktop browsers:
      • Google Chrome
      • Firefox
      • Safari
      • Microsoft Edge
      • Opera
    • Mobile browsers:
      • Safari for iOS
  • The latest release of the latest major version of:
    • Desktop browsers:
      • Firefox ESR
      • Internet Explorer
    • Mobile browsers:
      • Chrome for Android
      • Chrome for iOS
      • UC Browser
      • Opera Mini
      • Samsung Internet
  • Clarify what our browser support means.
    • Drupal accepts bug reports for supported browsers.
    • Contributors manually test significant changes in multiple browsers to watch for regressions, but this is somewhat based on the contributors available and the particular issue. We do not yet have full automated browser testing for our supported browsers.
    • By default, Drupal core does not accept bug fixes to unsupported browsers. Committers and the security team will assess the risk on a case-by-case basis and make exceptions to this rule when needed.
    • Drupal can start using any given browser feature once all the supported browsers have either native support or a polyfill. In each major release, polyfills that are no longer needed (because all supported browsers have added the feature natively) will be removed.

    Note: this also means that the ES5 JavaScript built from Drupal core's ES6 JavaScript targets only these browsers.
