The biggest visible change in this release is the switch to using TrueType fonts instead of bitmap fonts. This was necessary in order to properly support internationalization and also allowing people to chat in their own language when it wasn't using the Latin alphabet. Another nice feature that we hope to start using soon is support for animated tiles. This should allow mappers to make maps feel even more alive.
Translations in Brazilian Portuguese, Dutch, German and Danish are most complete, and incomplete translations for about two dozen other languages exist. Unfortunately due to not having time to figure out how to use gettext on Windows, the Windows installer doesn't have the new translations for now.
