This message is only important to those who follow the development version of the lme4 package at its R-forge SVN repository. The released version of lme4 is now called lme4.0 and the development version that was called lme4Eigen is now called lme4. As the new lme4 gains stability we will release the old version to CRAN as lme4.0 The reason for keeping the old version available as lme4.0 is because of other software and some publications that depend on the structure and component or slot names from that package.
Package name changes on the SVN repository at lme4.R-forge.R-project.org
