1.3.1

• Internal: Babel 6 and Flow definitions
• Bugfix: 1.3.0 broke string bounds ('parent', selectors, etc.).
• Bugfix: 1.3.0 wasn't updating deltaX and deltaY on a bounds hit.

1.3.0

• Possibly breaking change: bounds are calculated before <Draggable> fires drag events, as they should have been.
• Added 'none' axis type. This allows using <Draggable> somewhat like <DraggableCore> - state will be kept
  internally (which makes bounds checks etc possible), but updates will not be flushed to the DOM.
• Performance tweaks.

1.2.0

• Added arbitrary boundary selector. Now you don't have to just use 'parent', you can select any element
  on the page, including 'body'.
• Bugfix: Prevent invariant if a <Draggable> is unmounted while dragging.
• Bugfix: Fix #133, where items would eagerly start dragging off the mouse cursor if you hit boundaries and
  came back. This is due to how <DraggableCore> handles deltas only and does not keep state. Added new state
  properties slackX and slackY to <Draggable> to handle this and restore pre-v1 behavior.

1.1.3

• Bugfix: Server-side rendering with react-rails, which does bad things like mock window

1.1.2

• Bugfix: <Draggable> was calling back with clientX/Y, not offsetX/Y as it did pre-1.0. This unintended
  behavior has been fixed and a test has been added.

1.1.1

• Bugfix: Clean up scroll events if a component is unmounted before drag stops.
• Bugfix: NaN was returning from scroll events due to event structure change.
• Add scroll drag modulation test.

1.1.0

• Move grid into <DraggableCore> directly. It will continue to work on <Draggable>.
• Development fixes.

1.0.2

• Fix enableUserSelectHack not properly disabling.
• Fix a crash when the user scrolls the page with a Draggable active.

1.0.1

• Fix missing dist files for webpack.
• Ignore non-primary clicks. Added allowAnyClick option to allow other click types.

1.0.0

• Breaking: Removed resetState() instance method
• Breaking: Removed moveOnStartChange prop
• Breaking: React 0.14 support only.
• Refactored project.
• Module now exports a <DraggableCore> element upon which <Draggable> is based.
  This module is useful for building libraries and is completely stateless.
