+- Added `.float-{sm,md,lg,xl}-{left,right,none}` classes for responsive floats and removed `.pull-left` and `.pull-right` since they're redundant to `.float-left` and `.float-right`.
 - Added responsive variations to our text alignment classes `.text-{xs,sm,md,lg,xl}-{left,center,right}` and removed the redundant `.text-{left,center,right}` utilities as they are the same as the `xs` variation.
 - Dropped `.center-block` for the new `.mx-auto` class.
