This is a major version bump that has the following changes:

• Removed the font-family hack from Grids (#1074)
• IE is no longer supported and all code and documentation references have been removed
• The browserslist configuration has been updated to "> 1%" browser usage. You can use the browserslist tool to see which browsers this now covers.

Migration

This major version should not include too many breaking changes for your app, but please check the following:

• Since the list of supported browsers has now changed, please check that your site is still functioning in any browsers that you continue to support.
• Verify your grids are still functioning correctly with the font-family hack still removed. This should not affect you as it was a hack for older browsers.
