Here is a brief description of the final W2-F12 energies that are printed in the output file:

EW2F12VAL = -76.37450958 AU ! this is the nonrelativistic, valence CCSD(T)/CBS energy
EW2F12ALL = -76.43285033 AU ! this is the nonrelativistic, all-electron CCSD(T)/CBS energy
EW2F12ALLREL = -76.48468089 AU ! this is the relativistic, all-electron CCSD(T)/CBS energy

For further details see the Wn-F12 paper1 and these reviews.2,3
