Hi @craciunoiuc thanks for working through the integration process to get the Unikraft plugin updated. I've opened a PR internally to enable the integration once enabled you will be able to trigger a manual release notification job for version 0.2.0 to trigger a plugin ingestion from your integration portal. I'll circle back once the integration has been enabled.

Hi @craciunoiuc the integration has been enabled on our side. Could you run the notification job to test the integration ingestion please.
