A Delta release contains only those component versions created, inactivated or changed since the previous release. The ‘Delta’ release is much smaller than a ‘Full’ release and is ideal for updating a ‘Full’ release of the previous version. Adding a ‘Delta’ release to the previous version’s ‘Full’ release will update the installation to a ‘Full’ release of the current Version.
