 Phaser 3.13 introduces the new Facebook Instant Games Plugin. The plugin provides a seamless bridge between Phaser and version 6.2 of the Facebook Instant Games SDK. Every single SDK function is available via the plugin and we will keep track of the official SDK to make sure they stay in sync.

-## New Shape Game Objects
+### New Shape Game Objects
 
 Phaser 3.13 has a new Game Object called `Shape`, which by itself isn't much use because it's a base class. However, extending that class are 11 different types of Shape (with more to come) and you can use it to create your own custom Shapes as well. Shapes are added to the display list in the exact same way as any other Game Object. For example:

 The specificity if the input events has been changed to allow you more control over event handling.

 * The Game Object `gameobjectout` callback signature has a new argument. It now sends `event` as the 3rd argument.
 * The `pointerout` event, as dispatched by the InputPlugin, is now sent _after_ the Game Object specific events (`GameObject.pointerout` and `gameobjectout`). This gives you the chance to cancel the event before the global listener receives it.

+### Game Object List Updates
 
 When Sprite's are created they are added to two lists within the Scene - the Display List and the Update List. Under 3.12 when a Scene was shut down it would emit a `shutdown` event, which Sprites listened out for. When they received it, they would destroy themselves.

 * `GameObject.destroy` has a new optional boolean argument `fromScene`, which controls how the destroy process flows.

 * `Camera.pipeline` is the Pipeline that the Camera will render with if running under the WebGL Renderer and rendering to a texture with a pipeline set.
 * If you set a Camera to render to a texture then it will emit 2 events during the render loop. First, it will emit the event `prerender`. This happens right before any Game Object's are drawn to the Camera texture. Then, it will emit the event `postrender`. This happens after all Game Object's have been drawn, but right before the Camera texture is rendered to the main game canvas. It's the final point at which you can manipulate the texture before it appears in-game.

 * The Graphics Canvas Renderer will now automatically call `beginPath` on the target context before processing the command stack. This has the effect of clearing off any sub-paths that may have persisted on the stack from previous Graphics objects or frames. This makes it more in-line with WebGL re: expectations when calling `Graphics.clear`.
 * `initPipeline` now defaults to the Texture Tint Pipeline if nothing else is specified. This allowed me to remove explicit strings from 11 different Game Objects, saving some bytes in the process.

 * The `Text._lineSpacing` property has been renamed to `lineSpacing` and made public, not private. You still set it in the same way, by passing a `lineSpacing` property to the Text configuration object, but internally it's now clearer.

-## Bug Fixes
+### Bug Fixes
 
 * TileSprite.setTileScale would set the tile position by mistake, instead of the scale. Using the properties directly worked, but the method was incorrect (thanks @alexeymolchan)
 * Calling `Text.setStyle` would make the Text vanish if you didn't provide a `resolution` property in the style configuration object. Calling `setStyle` now only changes the properties given in the object, leaving any previously changed properties as-is. Fix #4011 (thanks @okcompewter)
