In preparation for an upcoming public beta release of Red Hat Satellite 6.3, current Satellite customers may notice Satellite 6.3 beta ISOs and packages available in their repositories.
Documentation, a Beta Navigation Guide, and customer support will be made available for the 6.3 beta at the time of public beta launch. The supported public launch of the Satellite 6.3 beta is currently scheduled for early December 2017. The announcement of the supported public beta will be made in the Red Hat Customer Portal and an email notification will be sent to all Red Hat Satellite customers at the time of the supported public beta launch.
Support will not be provided for the use of the Red Hat Satellite 6.3 beta software until the supported public beta is announced and open to all current Red Hat Satellite customers.
