Many key features of the GUI (like the knit button, running shiny apps, etc) depend on packages like rmarkdown, shiny, packrat, and devtools just to name a few. Sometimes I will be prompted that an updated version of one of these packages is required (
below) , and if I agree then the package is installed in my home directory library location for R packages. Is there a list or other site available that lists what the minimum required versions of these supporting packages? In our production environment for R we have a specific snapshot of CRAN with certain versions of packages installed in our default library, so it would be good to have this information as we upgrade RStudio to the latest release.
