Mixed-release environment

Licensed programs or their options do not always have the same release as the IBM® i operating system.

In addition to licensed programs not always being at the same release, they can be packaged so that the product's options are not at the same release as its base. This is referred to as a mixed-release environment. For these reasons, your IBM i 7.2 media might contain licensed programs and options that are at different releases than IBM i 7.2. Products that do not have any new function for this release are not repackaged, and therefore could have a release previous to IBM i 7.2. Licensed program releases and sizes contains information about the version, release, and modification level of the standard and keyed set products. You can also look at the product information to determine IBM i releases that are supported.
