I have seen this behaviour when I reduce the number of replicates to
0. I am assuming in your case with both the DESeq versions you are
using same number of replicates. Also in case you are not using
replicates at all then I believe it can affect the latest .DESeq
model. I am not sure about the version 1.2.

In the samples I'm working with, I see total DE genes going from ~200 - 2000 genes at FDR = 0.10 to nearly 0 genes using the new version at the same FDR.
