[BioC] new hexbin + adding points to hexbin plots

When I download hexbin from Bioconductor and then use library(hexbin) I get 
the message that I should download the newest version.

The old version is fine for what I want to do, except that I would like to 
add some points to the plot.

e.g.  an MA plot with controls highlighted

plot(MA$A[,1],MA$M[,1],main="MA plot")

I want to replace the first plot command with hexbin (so I can actually 
visualize the dense region of the plot), but I want to be able to add my 
points to the plot.

plot(hexbin(MA$A[,1],MA$M[,1]),main="MA plot")

does not give an error message.  But the points do not show up.

If the new version can do this, could someone please point me to the 
download site.
