+# Modern-browsers
+
+
+API for defining the boundary between modern and legacy JavaScript clients.
+
+You can use this package to define the minimum browser versions for which
+a browser engine will be considered modern. All browsers that do not meet
+the threshold will receive the legacy bundle. This way you can easily keep
+on using modern features that you need.
+
+You can read more about this in [Meteor 1.7 announcement blog](https://blog.meteor.com/meteor-1-7-and-the-evergreen-dream-a8c1270b0901).
