TOS 1.4.2 released

I've just released TOS 1.4.2, which includes the implementation for Prof. Kyrylov's recent wishes, especially the statistics gathering observer, and fixed player&ball positions during the PRE_GAME and HALF_TIME period. Others are minor GUI & network improvements, for example a disconnectted client can do an immediate reconnection.
