The package system really should ensure that older packages get replaced
when there
are rebuilt versions.

I do recall seeing instructions to remove all the currently installed
r-cran packages
before installing 3.5.   This is problematic -- some R users don't have
reliable internet
access so have to be very careful that all packages they use are installed
when they
have network access (think of people doing field work in remote areas or on
ships at sea).
