The 5-year WMAP data and analysis papers have been put on the web today. See:

and in particular

New precise limits are put on the scalar/tensor ratio, constraining many models of inflation. The rest of the numbers have smaller error bars. Especially interesting is that the curvature of the universe is flat to about 1% now, and the equation of state is still consistent with a cosmological constant. The epoch of reionization is found to be z~11.

Basically LCDM still works, with a 6 parameter fit.
