We just released 2.5.7 with plenty of new features and improvements

Here is the list of the most important news. The full list of changes can be seen inside the program (Main menu -> Info -> What's new).
Both new flat rides are recreations of classic fun fair rides. They are highly detailed with realistic sound effects. Also, they can be operated manually. Check out the Doppel Looping park where both rides were installed.
The new Script Parameter feature is a fundamental new option that will improve the usabilty of new scripted objects in the future a lot. They will allow the user to customize settings of the objects through the scene object instance panel, which can then be processed by scripts attached to the object. There are a lot of possibilities.
