Thanks for confirming! The current .iso does not seem to ship with the latest installer. This is not by itself an issue (albeit it would probably be nice to have an .iso with the latest version released), as the installer is able to self-update itself, but it feels as if the installer does not re-request a DHCP lease after kexec-loading into the new kernel after performing its self-update. Not sure if this is accurate though. I'll leave this bug to the screening team to assign it to the correct group.
