Unfortunatly I don't speak spanish, so I will answer in english (google doesn't translated it good enough, so I may be missing some points)
It's a preliminary version, with several features missing:
Preferences still doesn't work. But, soon will be.
Progress bar in "uploads" will be fixed too.
Friends and chat will be fixed in some distant future (I find it quite useless, but other may disagree).
List of clients per downloading file is still a problem, but may be solved.
