Important notice

KUSANAGI 8 based on CentOS 7 is planned to be delisted from the marketplace by the end of August 2024, as CentOS 7 will no longer be supported by the community by June 30, 2024.
As for the KUSANAGI 8 instances that have already been deployed, there will be no impact from the cloud side after the end of the availability, and our KUSANAGI RPM repository will remain for the time being, so they can continue to be used as is.
However, CentOS 7 will not be supported by the community after June 30, 2024, and we will not update the KUSANAGI RPM repository after KUSANAGI 8 reaches its end of life.
Therefore, from a security perspective, please consider migrating to KUSANAGI 9 on AlmaLinux OS 8 or other OS* as soon as possible.
