I'm brand new to Raspberry Pi. I ordered a Raspberry Pi 4 and it arrived today. Looking about I found the page on the RaspberryPi.org telling you how to update your packages. The following caught my attention:
However, there are occasional changes made in the Foundation's Raspberry Pi OS image that require manual intervention, for example a newly introduced package. These are not installed with an upgrade, as this command only updates the packages you already have installed.
My question is simply; Where are these new packages listed? Once I know what they are called I can work out if I have them or not (The SD card came pre-loaded) or if I still need to install them.
