- `sqlite = 3.30.1`
- `cloud_backup`
- `debian_linux = 9.0`
- `debian_linux = 10.0`
- `package_hub`
- `enterprise_linux_desktop = 6.0`
- `enterprise_linux_server = 6.0`
- `enterprise_linux_workstation = 6.0`
- `backports_sle = 15.0`
- `leap = 15.1`
- `mysql_workbench <= 8.0.19`
- `sinec_infrastructure_network_services < 1.0.1.1`
