         Spectrum has chosen the variant previously known as `quiet` to be the default and has added an `emphasized` variant with the same styles as the previous default.
         If you were using the `quiet` variant, the `.spectrum-Checkbox--quiet` class is no longer required and can be removed.
         If you need a switch to look like it did before this change, add `.spectrum-Checkbox--emphasized`.

+        Checkbox now supports t-shirt sizing and requires that you specify the size by adding a `.spectrum-Checkbox--size*` class.
+        Using the classes `.spectrum-Checkbox .spectrum-Checkbox--sizeM` will get result in the previous default checkbox size.
