Group.getAll will return all children in the Group, or a section of the Group, with the optional ability to test if the child has a property matching the given value or not.
Group.iterate has a new `returnType`: `RETURN_ALL`. This allows you to return all children that pass the iteration test in an array.
Groups have a new method `alignIn`. It allows you to align the Group within another Game Object, or a Rectangle. You can specify one of 9 positions which are the new position constants such as: `Phaser.TOP_LEFT` or `Phaser.CENTER` (see docs for the complete list). The Groups are positioned based on their child bounds, which takes rotation and scaling into consideration. You can easily place Groups into the corners of the screen, or game world, or align them within other Sprites, using this method.
Groups have a new method `alignTo`. It allows you to align a Group to the side of another Game Object, or a Rectangle. You can specify one of 11 positions which are the new position constants such as: `Phaser.TOP_LEFT` or `Phaser.LEFT_BOTTOM` (see docs for the complete list). The Groups are positioned based on their child bounds, which takes rotation and scaling into consideration. You can easily align Groups next to other Sprites using this method.
ArcadePhysics.Body.onOverlap is a new Signal that is dispatched whenever the Body overlaps with another Body. Due to the potentially high volume of signals this could create it is disabled by default. To use this feature set this property to a Phaser.Signal: `sprite.body.onOverlap = new Phaser.Signal()` and it will be called when an overlap happens, passing two arguments: the sprites which collided.
ArcadePhysics.World.separateCircle is a new method that handles all circular body collisions internally within Arcade Physics (thanks @VitaZheltyakov)
All of the Arcade Physics internal methods, such as `collideGroupVsSelf`, `collideSpriteVsSprite` and so on, have been updated to work with circular body shapes (thanks @VitaZheltyakov)
ArcadePhysics.Body.onWorldBounds is a new Signal that is dispatched whenever the Body collides with the world bounds, something that was previously difficult to detect. Due to the potentially high volume of signals this could create it is disabled by default. To use this feature set this property to a Phaser.Signal: `sprite.body.onWorldBounds = new Phaser.Signal()` and it will be called when a collision happens, passing one argument: the sprite on which it occurred.
* The PIXI.BaseTexture.imageUrl property has been removed, as it was never actually populated.
* The PIXI.BaseTexture._UID property has been removed, as it was never actually used internally.
* All references to PIXI.BaseTextureCache have been removed (primarily from BaseTexture.destroy and Texture.destroy), as the BaseTextureCache was never used internally by Phaser, or by our custom version of Pixi.
* PIXI.TextureCache has been removed. It was only ever used by the __default and __missing images that Phaser generates on start-up. It wasn't used internally by Phaser anywhere else, and the only references Pixi has to it have all been removed. If you need it in your own game, please refactor it to avoid it, or re-create the object on the PIXI global object.
* Canvases created by `BaseTexture.fromCanvas` no longer have the `_pixiId` property attached to them, as this was never used internally by Phaser or Pixi.
* PIXI.BaseTexture.updateSourceImage is now deprecated. Please use `Sprite.loadTexture` instead.
* The property PIXI.BaseTextureCacheIdGenerator has been removed, as it is no longer used internally by Phaser or Pixi.
* PIXI.Texture.addTextureToCache has been removed. The PIXI Texture Cache was never actually used by Phaser, and was leading to complications internally.
* PIXI.Texture.removeTextureFromCache has been removed. The PIXI Texture Cache was never actually used by Phaser, and was leading to complications internally.
* PIXI.Texture.fromFrame and PIXI.Sprite.fromFrame have been removed. They relied on the PIXI Texture Cache, which was never actually used by Phaser, and was never used internally by Pixi either.
* The property PIXI.TextureCacheIdGenerator has been removed, as it was not used internally.
* The property PIXI.FrameCache has been removed, as it was not used internally.
Graphics objects enabled for input would fail to do anything if a Phaser Polygon was given to the Graphics object (which it was in nearly all cases), as it wouldn't detect input correctly with flattened polygons (thanks @symbiane #2591)
BitmapData.copyTransform allows you to draw a Game Object to the BitmapData, using its `worldTransform` property to control the location, scaling and rotation of the object. You can optionally provide
BitmapData.drawGroup now uses the new `copyTransform` method, to provide for far more accurate results. Previously nested Game Objects wouldn't render correctly, nor would Sprites added via `addChild` to another Sprite. BitmapText objects also rendered without rotation taken into account, and the Sprites smoothing property was ignored. All of these things are now covered by the new drawGroup method, which also handles full deep iteration down the display list.
The `DisplayObject.worldScale` value didn't multiply the local objects scale into the calculation, meaning the value wasn't a true representation of the objects world scale.
Group.onChildInputUp is a new Signal that you can listen to. It will be dispatched whenever any immediate child of the Group emits an `onInputUp` signal itself. This allows you to listen for a Signal from the Group, rather than every Sprite within it.
Group.onChildInputOver is a new Signal that you can listen to. It will be dispatched whenever any immediate child of the Group emits an `onInputOver` signal itself. This allows you to listen for a Signal from the Group, rather than every Sprite within it.
Group.onChildInputOut is a new Signal that you can listen to. It will be dispatched whenever any immediate child of the Group emits an `onInputOut` signal itself. This allows you to listen for a Signal from the Group, rather than every Sprite within it.
InputHandler.dragTimeThreshold gives you more fine control over when a Sprite Drag event will start. It allows you to specify a time, in ms that the pointer must have been held down for, before the drag will begin.
InputHandler.downPoint is a new Point object that contains the coordinates of the Pointer when it was first pressed down on the Sprite.
