+Finalizing the translation workflow improvements and adding fixes for sounds missing in old game versions.
+
+### New or changed features
+
+- UI for the language settings has been unified across the application
+
+- GH-2209: Sounds in old (pre-1.6) versions should now work again
+
+  The launcher now downloads the correct assets and reconstructs the `resources` folder inside instances. This mirrors the same fix implemented in vanilla.
+
+  Also, a minor issue with the reconstruction being done twice per launch has been fixed.
