For our customer sites using the product Interaction Hub
Previously called Portal Solutions or Enterprise Portal, our product Interaction Hub is on a plan called the "release model of continuous delivery".
With this release model, Oracle delivers new functionality and enhancements on the latest release throughout the year, without requiring application upgrades to new releases.
Interaction Hub customers must upgrade to a PeopleTools release no later than 24 months after that PeopleTools release becomes generally available.
