I want to use https://firmware-selector.openwrt.org/ to add some extra packages to the packages included in release 20.03.0-rc4.
When I pick my router and expand "Customize installed packages" I see a populated list of packages, but some of the packages included in the official release (like uhttpd) are missing.
Where can I get a list of the packages included in a particular official release, so I can add to that list and provide the list to the firmware selector?
