The port of the Object I/O library to the Windows platforms will take approximately two or three months.

In a nutshell:
* The 0.8 I/O library supports only one interactive process at a time, the Object I/O library supports interleaved interactive processes.
* The state concept has been refined. It is now possible to introduce local state at any part of the graphical user interface. 
* Windows and dialogs have been made more orthogonal. Both windows and dialogs can contain controls. The layout of these elements has become more expressive. 
* All interactive components can be added and removed dynamically. 
* All interactive components can communicate with each other using message passing of arbitrary complex data structures.
 

Greetings,
