+## 6.2.0
+
+
+
+Add `SaveData<T>` for game progress and named save slots. Desktop games store
+public data fields as JSON in their user-data directory; the online IDE uses
+IndexedDB through the same Java API. Missing slots use caller-supplied defaults,
+while corrupt data and failed writes report errors without silently resetting
+progress. Writes commit before the game continues.
+
+The Coin Quest demo uses built-in assets and three slots, with controls to save,
+load and start a fresh round. Its score and sprite positions survive a desktop
+restart or browser reload.
+
+The demo launcher checks compilation before running an example, so newly added
+demos work even when older compiled classes are already present.
+
