Recommended target browsers

Drupal 8

Policy is to support these for each release of 8.x.x:

• Internet Explorer: 9+
• Microsoft Edge
• Firefox: Latest release, Latest Extended Support Release
• Chrome: Latest release
• Opera: Latest release
• Safari OSX: Latest release
• Safari iOS: Latest two releases (ios uptake has slowed)
• Android: 4+
• IE Mobile: 10+

As of 8.4.0

Beginning with the 8.4.0 release (due October 4, 2017), we will be dropping support for Internet Explorer 9 and 10. We will continue to support IE 11 and Microsoft Edge. This is because Microsoft themselves have ended support for these browsers and the operating systems they ran on.  It does not necessarily mean Drupal sites will stop working for IE 9 and 10 users, but we'll no longer require testing of core features with them.  

As of 8.0.x

• Internet Explorer: 9, 10, 11
• Microsoft Edge
• Firefox: 42, ESR 38.4.0
• Chrome: 46
• Opera: 33
• Safari OSX: 9
• Safari iOS: 8.3, 9.1
• Android: 4.1,4.2,4.3
• IE Mobile: 10
