v4.0.0

4.0.0 (2019-04-16)

Bug Fixes

• height animation when there are margins (4603503)
• move @babel/runtime to dependencies (addab3e)

BREAKING CHANGES

• now uses react-transition-context v5 by default, requiring
  React ^16.8.0.
• withTransitionContext and simpleWithTransitionContext have
  been removed.
• renderView no longer receives style, ref, key,
  etc. to pass along to the div it returns; rendering that wrapper div is
  now managed internally.
