Review Patch Documentation

When you install the application for the first time, you install either a base release (for example, 21.0) or a later patch release (for example, 21.0.1). If you are installing the base release or additional patches, read the documentation for all releases that have occurred since the base release before you begin installation. Documentation for patch releases can contain critical information related to the base release, as well as information about code changes since the base release.
