[3.0.0-rc2]
- Introduced a new behavior-flag: `middleCancel` determines if releasing a click from within the inner-radius will trigger the extended selection or the `defaultIndex` selection.
- `ChildRegion` is now referred to as `Slice` throughout the API.
- Style variables now have shorter names that resemble the `ButtonStyle` naming.
- `setDefaultIndex` now changes the `selectedIndex` if it isn't a valid index.
- The complementary callbacks (highlight and hover) are now regrouped within `PieMenuCallbacks`.
- Integrated rotations: scene2d's `rotateBy()` method is now supported.
- `radius` has been renamed to `minRadius` since it is now a suggested radius for the minimal radius value. In case `setFillParent(true)` or other size-changing methods are used (Table's `fill`, for example), the widget will now expand as a scene2d user would expect it to.
- `innerRadius` now designates a percentage of the radius, instead of an amount of pixels.
- Fixed the flicker resulting from hovering out of a contained Actor.
- `selectedColor` now used by default if no `downColor` was set: this is to prevent a flicker when clicking.
- Fixed a few `Animated` constructors.
- The `ShapeDrawer` is now instantiated internally.
- The default rules used by `ShapeDrawer` to determine the amount of sides to draw is now internally overridden with an improved algorithm.
- Added an example for adding Keyboard-Key-Mapping (selection through keyboard) on a `PieMenu`.

[3.0.0-rc1]
- Refactored the Style so that most of the `float` values (`radius` and the likes) have become class-attributes instead.
- Many more constructors available. Basic `float` properties (`radius` and the likes) are now integrated in the constructors.
- `PieMenuSuggestedClickListener` renamed to `PieMenuClickListener` and is now added by default. A setter is provided to change this `ClickListener` to a custom one.
- Added callbacks for mouse-over. Added the corresponding `hoveredChildRegionColor` and `hoveredAndSelectedChildRegionColor` to the `PieMenuStyle`.
- Added `highlightedChildRegionColor` in the `PieMenuStyle`.
- The `PieMenuClickListener` now triggers a highlight on `touchDown` rather than waiting for the mouse to move after the initial click.
- `HighlightChangeListener` renamed to `PieMenuHighlightChangeListener` and now extends EventListener. Removed the associated getter and setter: now `addListener()` should be used for that too.
- Widgets now start with their visibility set to `true` (it used to be `false`): this is to remain closer to scene2d's expected behavior.
- Changed the Actor-sizing algorithm (and thus fixed it for low `innerRadius` values).
- Integrated the propagation of the alpha from parent to children. Use the `setGlobalAlphaMultiplier(float)` method to do so.
- Fix for Widgets contained within a Table.
- Fix of the PieMenuStyle Colors-duplication.
- Style's `Circumference` values now include the `innerRadius` value.
- New API methods to allow more customization: `getActorDistanceFromCenter`, `getEstimatedRadiusAt`  and `modifyActor` can be changed to be whatever you want.
- Removed from the API the `@Deprecated` methods which should have been implemented by the users themselves anyway. This is reflected in the corresponding code-examples.
