Several people accused us of treason because we kept adding features after releasing RC2, which seems to be a capital crime in their eyes. Even more so as in addition to changing the SDK and several major components, we did not take the time to write a roadmap, as they would expect from any decent project.
Therefore, the name for RC3 necessarily had to be a traitor's name. Yes, I'm a cynic, I know
Anyway, since we now had one Greek traitor and another Greek project leader, the other names had to be Greeks, too. As the different releases are related to each other, their respective names are, too.
The choice of Pheidippides probably needs no further explanation. The release dates were chosen to lie on weekends, so we have time for the releases.
Pheidippides is planned for centenary of the battle of Marathon (in the Spartan calendar).
