All calls to Loader methods that add files to the queue, such as `Loader.image` or `Loader.atlas`, now have the URL as an optional parameter. If not set Loader will assume the URL to be based on the key given. For example the following: `game.load.image("boom", "boom.png")` can now be expressed as just `game.load.image("boom")`, or `game.load.atlas("player", "player.png", "player.json")` can now be shortened to `game.load.atlas("player")`. Please see the freshly updated jsdocs for full details.
SoundManager.pauseAll, resumeAll and stopAll now checks if the SoundManager.noAudio is set and ignores the calls.
SoundManager.usingWebAudio is set to `false` by default (used to be `true`) and is only explicitly set if Web Audio is available and hasn't been disabled in the PhaserGlobal object.
SoundManager.touchLocked is now set to `false` should the device be using legacy Audio, avoiding the unlock call running without need.
RenderTexture.render and `renderXY` would ignore the Sprites rotation or scale. The full Sprite transform is now used correctly when the Sprite is drawn to the texture. If you wish to replicate the old behavior please use `RenderTexture.renderRawXY` instead.
RenderTexture.matrix has been removed as it's no longer used.
Fixed bug in Pixi where RenderTexture.render would ignore the given matrix.
Fixed a bug in Pixi where drawing a Sprite to a RenderTexture would reset the Sprites transform to an identity Matrix.
Phaser.Matrix.copyFrom and copyTo allow you to copy Matrix values from and to other Matrix objects.
Phaser.Matrix.setTo allows you to set all properties of a Matrix in a single call.
The Phaser.Matrix constructor now allows you to optionally set all Matrix properties on instantiation.
Phaser.StateManager.created is a new read-only boolean that tells you if the State has finished running its `create` method. If it doesn't have one it's always true.
The StateManager would incorrectly call `loadRender` while the game was paused or if the State didn't have an `render` method defined even after the loader was completed.
Cache.getPixiBaseTexture will return a PIXI.BaseTexture from the cache based on the given key. A PIXI BaseTexture is created automatically for all images loaded and added to the cache.
Cache.getTexture has now been removed (it was deprecated several versions ago). Use Cache.getRenderTexture instead.
Cache.getJSON has a new optional parameter: `parse`. If `true` the method will pass the data through JSON.parse before returning it. The default is `false` to retain backwards compatibility.
Group.physicsSortDirection is a new property allowing you to set a custom sort direction for Arcade Physics Sprites within the Group hash. Previously Arcade Physics used one single sort direction (defined on `Phaser.Physics.Arcade.sortDirection`) but this change allows you to specifically control how each and every Group is sorted, so you can now combine tall and wide Groups with narrow and thin in a single system.
Physics.Arcade.sort now calls one of four functions: sortLeftRight, sortRightLeft, sortTopBottom and sortBottomTop. Each of which takes 2 Sprites as arguments.
Physics.Arcade.sort now doesn't bail out if the Group contains a mixture of physics and non-physics enabled objects, as the Group hash is now only ever populated with physics enabled objects. Also the sort comparison functions no longer return -1 if the bodies are invalid, but zero instead (#1721)
