I just find out
contains link to fedora prerelease version.
I don’t know, where to report it.
bugzilla.redhat.com seems to be for components and packages, not bad link.
Thanks for the report. The content on the installer is from the Fedora 42 GA compose. The pre-release warning is a configuration option in the tool that creates the ISO- we were late to get that removed in production and as a result we still have the warning.
The website will be updated shortly, or you can use an updated ISO found here.
