 ### Breaking
 
- * `Map::new`'s `tiles` parameter is now `Option`.
+ * `Tiles::new()` has now two parameters. First, called `source`, being a function transforming
+   `TileId` into an URL of a tile provider. This means that it's now possible to specify other
+   servers. `openstreeetmap` is a builtin function returning OSM's URL.
+ * `MapMemory` no longer has `osm` member. Instead, `Map::new`'s `tiles` parameter is now `Option`.
