[R-pkgs] New versions of Matrix and lme4 packages

[Douglas Bates]

I have uploaded version 0.96-1 of both Matrix and lme4 to CRAN.  The
source package should migrate to CRAN over the weekend and binary
packages should be available some time next week.

As for previous releases, the versions of these two packages are
interdependent.  The lme4 package requires Matrix_0.96-1 or later but
we cannot enforce the other dependency.  Please remember that if you
upgrade the Matrix package you should also upgrade the lme4 package.

The method for fitting generalized linear mixed models using the
Laplacian approximation is considerably faster in this version.  Also,
the packages have been reorganized so the interdependence will not be
as strong in the future.
