At Release

1. Merge upstream changes and put out a release:
   • Ignition
   • Afterburn
2. Merge metadata changes:
   • stream-metadata-go
   • stream-metadata-rust
   • fedora-coreos-tracker
   • fedora website
   • fedora-coreos-browser
3. Release updated components
   • Create and follow release checklist for stream-metadata-go
   • Ensure that Dependabot has PRed stream-metadata-go into fedora-coreos-stream-generator and coreos-assembler. Merge the update PRs.
     • This can be triggered manually by navigating to fedora-coreos-stream-generator's Dependabot and coreos-assembler's Dependabot respectively, then clicking "Check for updates".
       • This might need to be done a few times, as Dependabot might not pick up tag changes for a few attempts after initial tagging.
   • Create and follow release checklist for fedora-coreos-stream-generator
4. Merge the following changes:
   • coreos-assembler
5. Wait for updates made to coreos-assembler to be propagated to latest container
   • Download latest version of coreos-assembler container. Verify platform support functionality.
6. Merge changes for:
   • Build pipeline
7. Wait for new images to reach stable then merge documentation.
   • fedora-coreos-docs merged

Add a stanza to platforms.yaml if the system should use a serial console, or both serial and graphical consoles

@travier mind helping me to know if this is needed?

Add a stanza to platforms.yaml if the system should use a serial console, or both serial and graphical consoles

I'll check again when testing the image.

When testing this, I immediately got console output on boot with the online console access. So I would say that we don't need to do anything more.

I've also verified that both Ingnition and Afterburn appears to be working as expected.

I've updated the docs at coreos/fedora-coreos-docs#654 to use those upcoming images.
