The new Bologna TT world 6 (yes, it is a whole separate world with just a single route) can only be accessed in events. You cannot world hack to it 🙁
You still have several chances to access it in different events, though. You can easily find out which ones here: http://staging1792839621.zwifthacks.com/app/events/?key=5cdabd1fdb12b
The latest update of Zwift brings France and Paris into the regular guest world rotation. Even better, you can world hack into both France and Paris with zwift-preferences / ZwiftPref. You don’t even have to update anything – it just works because zwift-preferences and ZwiftPref automatically pull configuration data from the ZwiftHacks server.
See the route listing at http://staging1792839621.zwifthacks.com/app/routes/?filter=new!
The new Makuri Islands world is supported by all of these ZwiftHacks tools: Events Routes zwift-preferences ZwiftPref An update for ZwiftMap may still be needed but it will be done server-side and does not require that you download anything. It will follow soon.
Which worlds are open today? Which events can I join today? What are the routes available in the open worlds? These questions can be answered from the new Zwift Today page with the easy to remember URL zwifthacks.com/today
