first, I'd recommend holding off with updating packages. Due to the number of packages, updating all of them takes quite some time, so in order to use the binaries that are built with the release version of R it will probably take at least until tomorrow that they are propagated through the mirror network. Hence you'll have to re-install them anyway if you do it now. 

That said, the "select packages from previous version" search function only applies to the system library - the use library is not in scope. However, where you install those packages is up to you depending on the selection in the Package Installer - the two steps are separate in the GUI.
