* This allows to generate interesting visual effects, which can be controlled by events. For example, you can use an outline on an object to highlight, make the player glow when launching a spell, blur objects, etc...
* A new "effects" tab is now present in the objects editor. From there, you can add visual effects, that were already available for layers, customize them from this editor.
* Actions and conditions are available to manipulate effects and change their parameters during the game.

* Allow to choose the style of the GDevelop logo (light, dark, colored or plain)
* Allow to choose the background color and an optional background image
* Allow to choose the size of the progress bar (with a minimum and maximum size)
* Allow to choose the duration of the fade in animations and the minimum time the loading screen is shown
* Use the **new preview button in the game properties** dialog to run a preview with the loading screen shown
* This removes toJSON method on gdjs.Variable. This was just introduced in beta 111, if you're using it, please use toJSObject instead and JSON.stringify.
* This allows to display texts on screen that use a "bitmap font", generated with softwares like [BMFont](https://www.angelcode.com/products/bmfont/) or [bmGlyph](http://www.bmglyph.com/).
* Bitmap fonts allow advanced effects and custom design of each character, with complete control over the appearance of the text. This is useful for making a custom score counter, titles, button labels...
* They also render very well in a pixel-perfect, pixel-art or retro-like game.
* Finally, these Bitmap Texts are fast and efficient to render on screen: useful for scores or texts that are updated frequently.
* This is useful for making concise actions or conditions.
* This is also useful because for some objects, the center is not located at half the width and the height of the object.
* You can use `Object.CenterX()` and `Object.CenterY()` to get the position of the center of an object in an expression.
* This fixes some "flickering" when a sprite is just created, when a scene is changed or when external layout objects are created on a scene.
Fixes#1285
* Because of this, this could create some glitches when playing sounds using the condition to check if a sound was already playing (for example, it could trigger multiple times a sound).
* In the list of variables (of the scene, of an object or global variables), you can now specify the type of the variable: number, text, boolean, array or structure.
* Boolean variables can be "true" or "false. They can have their values checked with conditions, and updated with actions. They are a good way to store information about if something is enabled or not (is an item equipped, is something selected, etc...).
* Array variables can contain multiple values, indexed by a number. New values, including any kind of variables, can be appended to an array during the game. Arrays can also have a value removed, and using the event "For each child variable", you can run conditions and actions for each value that is present in the array.
* Boolean and arrays are also supported when you transform a variable from or to the JSON format - which is ideal to send web requests, read configuration files or store any kind of arbitrary data.
* Finally, note that array values can themselves be arrays, structures or any variable. This can be useful to construct advanced logic. You can also access arrays (as well as any variable) from JavaScript code block events.
* When marked as preloaded, the audio file is loaded in memory and ready to play. When played using an action, it will start almost immediately.
* There are also new actions to unload some or all audio files from memory. This can be useful when switching between levels in large games.
* This allows to set the position of a sound in a 3D space. The stereo system of the device is used to simulate the position of the sound and to give the impression that the sound is located somewhere around the player.
* Banners can't be overlayed on the game anymore. It's displayed either above or below.
* New conditions to check if interstitials, banner or reward videos encountered an error when loading.
* New action to set up the test mode for all ads at once
* App Id are now separated, with one for Android and one for iOS. Don't forget to update them before exporting your app, otherwise it would get terminated when started.
