Mandrake has announced
the start of the testing cycle for 10.1. A new schedule
for the release of 10.1 has been announced also.
Iso files are available too. These files are basically a Cooker snapshot.
I installed this in a spare partition and its in pretty good shape. Most of the problems I saw with Cooker lately have been fixed. The only thing I really noticed is that firefox isn't working yet. The install program had a few glitches but worked.
The point of test releases is to catch bugs before the official release. If you have the skills you might want to try this out.
