Windows Binary lme4a from R-forge

I tried to download the Windows binary of lme4a today, but it is missing in

http://r-forge.r-project.org/bin/windows/contrib/2.11/


The lme4b version which "should never see the light of day" according to
Douglas Bates, is available. So is this version the born eventually, and
does it supersede lme4a?
