Where is XML list of Flow pre-release versions?

Flow

I am trying to access the pre-release version of Vaadin 12, as [discussed on Stack Overflow]
(https://stackoverflow.com/q/53028557/642706).

I copied the prerelease related Maven POM configuration settings from a Vaadin 8 project’s pom.xml. Unfortunately, those settings refer to this site:

http://maven.vaadin.com/vaadin-prereleases

… which does lists items for pre-release versions of Vaadin 7 and Vaadin 8, but none for Vaadin Flow (10, 11, 12, and so on).

Is there another pre-release site listing versions for Flow?

Or is there some other route I should be taking to access pre-release versions of Flow?

The link you posted lists pre-releases for the Vaadin platform too, for example
http://maven.vaadin.com/vaadin-prereleases/com/vaadin/vaadin/
and
http://maven.vaadin.com/vaadin-prereleases/com/vaadin/vaadin-bom/

True that there are no archetypes for these, but that’s not necessary when one can instead use the starters from https://vaadin.com/start.
