Update Notifier doesn't notify of a new available version either. Changing "Notify me of a new Ubuntu version" from "For long-term support versions" to "For any new version" makes Update Notifier aware of it. This step is identical to manually editing the file /etc/update-manager/release-upgrades.
The reason is that 20.04.1 is still marked as a development release.
