A general description is here.
R CMD INSTALL --with-package-versions is deprecated (and support has always been incomplete on Windows).
Using plot.lm() on a "glm" object since 2.7.1 with which=5 caused the Pearson rather than deviance residuals to be used in which=2 or 3 (including in the default case). (Thanks to Effie Greathouse and Greg Snow.)
plot.lm() did not report on omitting observations with leverage one if they also had residual exactly zero. This was seen in example(occupationalStatus).
