 The plugin entry point, ie. the `TiledMapBundle` bundle is gone.
 It was cumbersome and did not allow for a proper separation of concerns (for instance, for physics).
 
-Also, the `Handle<TiledMap>` type is not a Bevy component anymore, since Bevy `Handle<T>` now cannot derive the `Component` trait.
+Also, the `Handle<TiledMap>` type is not a Bevy component anymore.
+It was done in order to anticipate expected changes in Bevy where `Handle<T>` won't be able to derive the `Component` trait anymore.
 
 Anyway, the new way to spawn a map is now easier: you just have to spawn a `TiledMapHandle` referencing your .TMX file asset:

+## Misc changes
+
+### `TiledMapSettings` update
+
+`map_initial_transform` and `map_initial_visibility` have been removed from `TiledMapSettings`.
+
+If you want to tweak your map positioning or visibility, you should instead directly insert corresponding `Transform` or `Visibility` components on it.
+
+Before:
+
+```rust,no_run
+    let map_handle: Handle<TiledMap> = asset_server.load("map.tmx");
+    commands.spawn((
+        TiledMapHandle(map_handle),
+        TiledMapSettings {
+            map_initial_transform: Transform::from_xyz(150., 100., 0.),
+            map_initial_visibility: Visibility::Hidden,
+            ..Default::default()
+        },
+    ));
+```
+
+After:
+
+```rust,no_run
+    let map_handle: Handle<TiledMap> = asset_server.load("map.tmx");
+    commands.spawn((
+        TiledMapHandle(map_handle),
+        Transform::from_xyz(150., 100., 0.),
+        Visibility::Hidden,
+    ));
+```
