v0.7.0

Fixed

• Fixed the UnPivot.convert method not modifying the original data object.
• Axis line, labels, ticks, interlacing and guide can be set to auto.
• Simple fade in case of empty target chart
• Fixed length serialization in style() for % unit.
• Fixed missing rendering update when duration is 0 in first animate call.
• Fixed error on multiple calls of the JS chart's 'data' property.
• Fixed disapearing title from empty charts.
• Fixed animation cancelling, did not trigger promise rejection.
• Fixed chart state reset on animation cancel. Used the target chart's config
  further on despite the cancellation.
• Fixed the type definition of Snapshot in the d.ts file.

Added

• 'regroupStrategy' animation option introduced to control the algorithm for
  transitioning between charts having the data grouped differently on them
  (containing a different set of categorical dataseries).
• Multi keyframe animation support (one animation through multiple chart).
• 'style' property returns the style object only filled with the user-set
  values, all the values (returned by this property till 0.6.x) can be get
  using the new 'getComputedStyle()' method.
• detach() method added to JS API for enabling proper garbage collection.
• Actual animation can be stored for later reuse through Anim.Control.store()
  method.
• animate() returned promise is not an animation controller object from now on,
  but has a member promise called 'activated', which resolves to the controller.
• New style parameter, 'numberScale' has been introduced for setting the scale
  system for big numbers e.g.: K M B T or k m bn tn.
• Improved default options for animations: marker geometry, marker fade-in,
  marker position, coordinate system, title.
