Bootstrap 4 browser support version

Question

I am working on a new website and plan to use Bootstrap 4. Since its still in alpha stage, it is somewhat risky. Bootstrap docs mentions that all the latest browsers are supported but does not specify from which version on.

So is it possible to know that from which browser version is bootstrap 4 supported?

Answer 1

The list of supported browsers can be found in the "package.json" file once you download bootstrap. It's also written on the bootstrap website in the documentation.
Here's the list of supported browsers for v4:

Chrome 45+
Firefox 38+
Opera 30+
Internet Explorer 10+
Edge 12+
iOS 9+
Safari 9+
Android 4.4+

Answer 2

From bootstrap web site,

Bootstrap supports the latest, stable releases of all major browsers and platforms. On Windows, we support Internet Explorer 10-11 / Microsoft Edge.

They mentioned all stable major releases are supported. With supporting ESR versions. Im not so sure but they meant by it, that currently latest browser versions and all future versions could handle bootstrap 4 as it should be.

Answer 3

Supported Browsers are:

"last 1 major version",
  ">= 1%",
  "Chrome >= 45",
