  We present a new abundance analysis of HE 1327-2326, the currently most
iron-poor star, based on observational data obtained with VLT/UVES. We correct
the 1D LTE abundances for 3D effects to provide an abundance pattern that
supersedes previous works, and should be used to observationally test current
models of the chemical yields of the first-generation SNe. Apart from
confirming the 1D LTE abundances found in previous studies before accounting
for 3D effects, we make use of a novel technique to apply the 3D-1D corrections
for CNO which are a function of excitation potential and line strength for the
molecular lines that comprise the observable CH, NH, and OH features. We find
that the fit to the NH band at 3360 A is greatly improved due to the
application of the 3D-1D corrections. This may indicate that 3D effects are
actually observable in this star. We also report the first detection of several
weak Ni lines. The cosmologically important element Li is still not detected;
the new Li upper limit is extremely low, A(Li)<0.62, and in stark contrast with
results not only from WMAP but also from other metal-poor stars. We also
discuss how the new corrected abundance pattern of HE 1327-2326 is being
reproduced by individual and integrated yields of SNe.
