  Recently, two issues concerning the three-year WMAP likelihood code were
pointed out. On large angular scales ($l \lesssim 30$), a sub-optimal
likelihood approximation resulted in a small power excess. On small angular
scales ($l \gtrsim 300$), over-subtraction of unresolved point sources produced
a small power deficit. For a minimal six-parameter cosmological model, these
two effects conspired to decrease the value of $n_s$ by $\sim 0.7 \sigma$. In
this paper, we study the change in preferred parameter ranges for more
extensive cosmological models, including running of $n_s$, massive neutrinos,
curvature, and the equation of state for dark energy. We also include
large-scale structure and supernova data in our analysis. We find that the
parameter ranges for $\alpha_s$, $\Omega_k$ and $w$ are not much altered by the
modified analysis. For massive neutrinos the upper limit on the sum of the
neutrino masses decreases from $M_\nu < 1.90$eV to $M_\nu < 1.57$eV when using
the modified WMAP code and WMAP data only. We also find that the shift of $n_s$
to higher values is quite robust to these extensions of the minimal
cosmological model.
