Hello lmer experts

In the past the lmer function allowed to choose either ML or REML as the
estimation method.

I just updated the R version  to *R version 2.8.0* (2008-10-20)
(i386-pc-mingw32)  and the lme4 package to *lme4_0.999375-27.


*I am running my old code choosing ML as the estimation method and I am
getting this warming:

Warning message:
In lmer(meansize ~ year + (year | id), data = cas, method = "ML") :
  Argument 'method' is deprecated.  Use 'REML' instead


This is my code:

model.a<-lmer(meansize~year+ (year|id),data=cas, method="ML")


I have tried to look for the asnwer myself in the R-sig-mixed message board
and I could not find an answer.

Does anybody understand the reason why ML cannot be used anymore?

Thanks in advance.

Maria
