I would like to know if any progress has been made on Hadamard conjecture : There exists a Hadamard matrix of order $n=4k$ $\forall k \in \mathbb{N}$.

The wikipedia article seems up to date. –  Chris Godsil Jan 8 '12 at 18:48
Warwick de Launey's paper "On the Asymptotic Existence of Hadamard Matrices", arxiv.org/abs/1003.4001, may be of interest. –  Will Orrick Jan 8 '12 at 19:45
