Still have 22.214.171.12438 and 126.96.36.19903 in my PC, they are working very well ! Now I'm mainly use 3.2.2, it is fine too. However, 3.3.0(28120) are not good. Even though it has so much enhancement, multi-thread I/O etc. It connect much less peers than 3.2 and 2.x, and the transmission speed (U/D) is very low.
