+### Updates
+- New scripting API features : 
+  - Use `WA.room.loadTileset(url: string) : Promise<number>` to load a tileset from a JSON file.
+- Rewrote the way authentification works: the auth jwt token can now contains an email instead of an uuid
+- Added an OpenId login flow than can be plugged to any OIDC provider.
+- You can send a message to all rooms of your world from the console global message (user with tag admin only).

 ### Updates

 - Migrated the admin console to Svelte, and redesigned the console #1211
 - Layer properties (like `exitUrl`, `silent`, etc...) can now also used in tile properties #1210 (@jonnytest1)
 - New scripting API features :
+  - Use `WA.onInit(): Promise<void>` to wait for scripting API initialization
   - Use `WA.room.showLayer(): void` to show a layer
   - Use `WA.room.hideLayer(): void` to hide a layer
   - Use `WA.room.setProperty() : void` to add, delete or change existing property of a layer
   - Use `WA.player.onPlayerMove(): void` to track the movement of the current player
-  - Use `WA.player.getCurrentUser(): Promise<User>` to get the ID, name and tags of the current player
+  - Use `WA.player.id: string|undefined` to get the ID of the current player
-  - Use `WA.room.getCurrentRoom(): Promise<Room>` to get the ID, JSON map file, url of the map of the current room and the layer where the current player started
+  - Use `WA.player.name: string` to get the name of the current player
-  - Use `WA.ui.registerMenuCommand(): void` to add a custom menu
+  - Use `WA.player.tags: string[]` to get the tags of the current player
+  - Use `WA.room.id: string` to get the ID of the room
+  - Use `WA.room.mapURL: string` to get the URL of the map
+  - Use `WA.room.mapURL: string` to get the URL of the map
+  - Use `WA.room.getMap(): Promise<ITiledMap>` to get the JSON map file
   - Use `WA.room.setTiles(): void` to add, delete or change an array of tiles
+  - Use `WA.ui.registerMenuCommand(): void` to add a custom menu
+  - Use `WA.state.loadVariable(key: string): unknown` to retrieve a variable
+  - Use `WA.state.saveVariable(key: string, value: unknown): Promise<void>` to set a variable (across the room, for all users)
+  - Use `WA.state.onVariableChange(key: string): Observable<unknown>` to track a variable
+  - Use `WA.state.[any variable]: unknown` to access directly any variable (this is a shortcut to using `WA.state.loadVariable` and `WA.state.saveVariable`)
 - Users blocking now relies on UUID rather than ID. A blocked user that leaves a room and comes back will stay blocked.
 - The text chat was redesigned to be prettier and to use more features :
-  - The chat is now persistent bewteen discussions and always accesible
+  - The chat is now persistent between discussions and always accessible
   - The chat now tracks incoming and outcoming users in your conversation
   - The chat allows your to see the visit card of users
   - You can close the chat window with the escape key

+
+## Saving / loading state
+
+The `WA.state` functions allow you to easily share a common state between all the players in a given room.
+Moreover, `WA.state` functions can be used to persist this state across reloads.
+
+```
+WA.state.saveVariable(key : string, data : unknown): void
+WA.state.loadVariable(key : string) : unknown
+WA.state.onVariableChange(key : string).subscribe((data: unknown) => {}) : Subscription
+WA.state.[any property]: unknown
+```
+
+These methods and properties can be used to save, load and track changes in variables related to the current room.
+
+Variables stored in `WA.state` can be any value that is serializable in JSON.
+
+Please refrain from storing large amounts of data in a room. Those functions are typically useful for saving or restoring
+configuration / metadata.
+
+{.alert.alert-warning}
+We are in the process of fine-tuning variables, and we will eventually put limits on the maximum size a variable can hold. We will also put limits on the number of calls you can make to saving variables, so don't change the value of a variable every 10ms, this will fail in the future.
+
+
+Example :
+```javascript
+WA.state.saveVariable('config', {
+    'bottomExitUrl': '/@/org/world/castle',
+    'topExitUrl': '/@/org/world/tower',
+    'enableBirdSound': true
+}).catch(e => console.error('Something went wrong while saving variable', e));
+//...
+let config = WA.state.loadVariable('config');
+```
+
+You can use the shortcut properties to load and save variables. The code above is similar to:
+
+```javascript
+WA.state.config = {
+    'bottomExitUrl': '/@/org/world/castle',
+    'topExitUrl': '/@/org/world/tower',
+    'enableBirdSound': true
+};
+
+//...
+let config = WA.state.config;
+```
+
+Note: `saveVariable` returns a promise that will fail in case the variable cannot be saved. This
+can happen if your user does not have the required rights (more on that in the next chapter).
+In contrast, if you use the WA.state properties, you cannot access the promise and therefore cannot
+know for sure if your variable was properly saved.
+
+If you are using Typescript, please note that the type of variables is `unknown`. This is
+for security purpose, as we don't know the type of the variable. In order to use the returned value,
+you will need to cast it to the correct type (or better, use a [Type guard](https://www.typescriptlang.org/docs/handbook/2/narrowing.html) to actually check at runtime
+that you get the expected type).
+
+{.alert.alert-warning}
+For security reasons, the list of variables you are allowed to access and modify is **restricted** (otherwise, anyone on your map could set any data).
+Variables storage is subject to an authorization process. Read below to learn more.
+
+### Declaring allowed keys
+
+In order to declare allowed keys related to a room, you need to add **objects** in an "object layer" of the map.
+
+Each object will represent a variable.
+
+<div class="row">
+    <div class="col">
+        <img src="https://workadventu.re/img/docs/object_variable.png" class="figure-img img-fluid rounded" alt="" />
+    </div>
+</div>
+
+The name of the variable is the name of the object.
+The object **type** MUST be **variable**.
+
+You can set a default value for the object in the `default` property.
+
+### Persisting variables state
+
+Use the `persist` property to save the state of the variable in database. If `persist` is false, the variable will stay
+in the memory of the WorkAdventure servers but will be wiped out of the memory as soon as the room is empty (or if the
+server restarts).
+
+{.alert.alert-info}
+Do not use `persist` for highly dynamic values that have a short life spawn.
+
+### Managing access rights to variables
+
+With `readableBy` and `writableBy`, you control who can read of write in this variable. The property accepts a string
+representing a "tag". Anyone having this "tag" can read/write in the variable.
+
+{.alert.alert-warning}
+`readableBy` and `writableBy` are specific to the "online" version of WorkAdventure because the notion of tags
+is not available unless you have an "admin" server (that is not part of the self-hosted version of WorkAdventure).
+
+Finally, the `jsonSchema` property can contain [a complete JSON schema](https://json-schema.org/) to validate the content of the variable.
+Trying to set a variable to a value that is not compatible with the schema will fail.
+
+
+## Tracking variables changes
+
+The properties of the `WA.state` object are shared in real-time between users of a same room. You can listen to modifications
+of any property of `WA.state` by using the `WA.state.onVariableChange()` method.
+
+```
+WA.state.onVariableChange(name: string): Observable<unknown>
+```
+
+Usage:
+
+```javascript
+WA.state.onVariableChange('config').subscribe((value) => {
+    console.log('Variable "config" changed. New value: ', value);
+});
+```
+
+The `WA.state.onVariableChange` method returns an [RxJS `Observable` object](https://rxjs.dev/guide/observable). This is 
+an object on which you can add subscriptions using the `subscribe` method.
+
+### Stopping tracking variables
+
+If you want to stop tracking a variable change, the `subscribe` method returns a subscription object with an `unsubscribe` method.
+
+**Example with unsubscription:**
+
+```javascript
+const subscription = WA.state.onVariableChange('config').subscribe((value) => {
+    console.log('Variable "config" changed. New value: ', value);
+});
+// Later:
+subscription.unsubscribe();

+# Writing text on a map
+
+## Solution 1: design a specific tileset (recommended)
+
+If you want to write some text on a map, our recommendation is to create a tileset that contains
+your text. You will obtain the most pleasant graphical result with this result, since you will be able
+to control the fonts you use, and you will be able to disable the antialiasing of the font to get a 
+"crispy" result easily.
+
+## Solution 2: using a "text" object in Tiled
+
+On "object" layers, Tiled has support for "Text" objects. You can use these objects to add some
+text on your map.
+
+WorkAdventure will do its best to display the text properly. However, you need to know that:
+
+- Tiled displays your system fonts.
+- Computers have different sets of fonts. Therefore, browsers never rely on system fonts
+- Which means if you select a font in Tiled, it is quite unlikely it will render properly in WorkAdventure
+
+To circumvent this problem, in your text object in Tiled, you can add an additional property: `font-family`.
+
+The `font-family` property can contain any "web-font" that can be loaded by your browser.
+
+{.alert.alert-info}
+**Pro-tip:** By default, WorkAdventure uses the **'"Press Start 2P"'** font, which is a great pixelated
+font that has support for a variety of accents. It renders great when used at *8px* size.
