Here is the third alpha of Mageia 3 (released on November 14th, 2012) This is alpha software. This means, it is NOT:
for daily use,
for any kind of productive use,
for writing any kinds of reviews.
It is a testing release for finding bugs, to look out for important missing packages, a platform for further development leading to the beta stage and finally our first official release planned in March 2013.
