Convention for Referring to Release Numbers in Upgrade Topics

Review to understand how statements in upgrade topics apply to releases.

When a statement is made in an Oracle Database upgrade topic about an annual Oracle Database release, that statement applies to the entire release. A statement about Oracle Database 21c, Oracle Database 19c, or any other release supported for direct upgrade, applies to all component-specific and platform-specific releases within that release, unless otherwise specified.

When a statement is made about a specific quarterly release update (RU, or Update), that statement applies to that quarterly Update.
