RStudio Server Pro
Note: RStudio Server Pro now requires a Postgres database when using its internal load balancer; this database must be set up prior to upgrade from earlier releases. If you have a multi-node RStudio Server Pro installation, consult the Administration Guide for instructions before upgrading.
Note: RStudio Server Pro uses a new location for user state; .rstudio is now .local/share/rstudio. This is a breaking change if you have symlinked .rstudio and can make downgrade more complicated. See the Administration Guide for more information, including instructions for using the old location if desired for compatibility with previous releases.
