So now you're starting with Boinc, heh Brucifer?

Tanpaku is so far a rock solid project. Strangely it is the second boinc project I see that enforces boinc v4. The other one is Cell Computing, also Japanese.
Knowing I that the last versions of the v4 round were very stable and that the switch to all the new v5 features was what brought in so many problems, I'd say they follow the rule "If it's working, don't mess with it"
The japanese people are smarter on that than us western folks that try to "be on the bleeding edge" with the latest version all the time. :roll:
