CHANGES in `coin' VERSION 1.0-10 o improve upon `qperm' for van de Wiel algorithm again. CHANGES in `coin' VERSION 1.0-9 o again precision problems in van de Wiel algorithm: `qperm' suffered from too large tolerances of the inverted probability function. CHANGES in `coin' VERSION 1.0-8 o precision problems in van de Wiel algorithm fixed. In rare cases, P(T < t) was returned as p-value instead of P(T <= t).
