Update of the 2009 averages for the PDG 2010 edition:

main differences w.r.t. previous averages:

We now use a new program to compute F(1)|Vcb| for the B->D*+lnu decays.  While the central values obtained with the two different codes are very similar (at the % level), the confidence level reported from the new code is considered more reliable than the previous code. More studies are being pursued on this issue.

We report for the first time the average for B->etalnu decays.
