New Poseidon 4.0 GNU/Linux is here!

For now, the 32 bits version was released; but soon, the 64 bits version will be released, also. This new release is based on the Long Term Support Ubuntu 10.04 (with 3 years of updates guaranteed by Canonical), since our goals are stability, usability and support for the whole system when used professionally at universities, institute, colleges and -also- at home.
