A general description is here.
R CMD check now also checks if the package and namespace can be unloaded: this provides a check of the .Last.lib() and .onUnload() hook functions (unless --install=fake).
An error when unloadNamespace() attempted to run the .onUnload() function gave an error in the reporting function and so was not reported properly.
Text help rendering did not handle very long input lines properly.
available.packages() cwould fail when run on a small repository repository with no packages meeting the filtering conditions. (PR#14042).
rep(x, times, each= = 2) gave invalid results when the 'times' argument is a vector longer than 'x'. Reported by Bill Dunlap.
