@sayanchowdhury Looks like 3815.2.5 is not on azure similar to the last several times. Is there a plan to add it?

[tormath1]

@ericgraf we just released and submitted Flatcar releases to Azure for publishing. It usually takes a few hours / days to Azure to publish the changes.

Submitted to GCP and started validation. Will check back later if it succeeded, otherwise publish tomorrow. Validation concluded, new release is now live on GCP.

@ericgraf The Azure CoreVM offers flatcar-container-linux-corevm (which is arm64) and flatcar-container-linux-corevm-amd64 have passed validation and are currently being published (==replicated across geo-regions). These offers should have the update available really soon.

The offers flatcar-container-linux-free and flatcar-container-linux are still undergoing Azure marketplace validation. We'll publish as soon as these have passed.

The offer flatcar-container-linux-free passed the validation and has been published. The last flatcar-container-linux is getting published and should be soon available.
