We're beginning our first project using Zurb Foundation. We're on v6.2.4 and will switch to v6.3.0 when available. We'd like to clarify the browser support for Zurb's implementation of flex grid.
On this page: http://foundation.zurb.com/sites/docs/flex-grid.html, Zurb states, "The flex grid is only supported in Chrome, Firefox, Safari 6+, IE10+, iOS 7+, and Android 4.4+." But there's also this link on this same page: View flexbox browser support which seems to indicate that IE10 doesn't support flexbox, and IE11 only partially supports flexbox.
Which documentation source is correct regarding browser support for Zurb's flexbox and flex grid implementations?
