+==== Version 0.3.1 ====
+
+Released on 2013-08-04.
+
+  * Fixed a bug with the savegame system: audio was not restored after loading a savegame. Also, when loading an asset fails the other assets are not affected by it. Savegames made with 0.3.0 should still work with this release.
+
+==== Version 0.3.0 ====
+
+  * Better support for %, e.g. to allow WebStories with fluid stage dimensions.
+  * New Background asset that stretches to fit the stage.
+  * Engine split into separate files for development to be more modular.
+  * Alpha support for local container apps.
+  * WSE object gets it's own data bus, to allow obtaining game and interpreter references at startup.
+  * Textbox asset gets an HTML-aware typewriter effect.
+  * Use HTML in <line> commands directly, without the ugy {tag} syntax.
+  * New side images extension.
+  * Updated savegame API to make it more robust and easier to use. Also fixes: [[https://github.com/jsteinbeck/WebStory-Engine/issues/4|GitHub issue #4]]
+  * Extend the Textbox definition with a <nameTemplate> element, in which {name} will be replaced by the name of the character who's speaking, if any.
