Ah!  I looked at this for a moment, and discovered a problem with the automatic build promotions!  I don't know which flavour of image this is, but presumable production.  We should fix that problem with the CI build process, and then get this updated to reflect that.

The image will end up in https://downloads.puppetlabs.com/razor/iso/prod/razor-microkernel-latest.iso - note the `prod` in that path - in a few minutes, to separate out the flavours.
