lmer function.

I am using the lmer function from the lme4 package.  I wrote the 
following statement, specifying the method to be adaptive Gaussian 
quadrature. I am getting an error saying "method = "AGQ" not yet 
implemented for supernodal representation".  Please help.

 > fit <- 
lmer(response~beta1+(1|patient),family=binomial,method="AGQ",data=data.2)
