Last updated on FEBRUARY 01, 2024

Applies to:

Information in this document applies to any platform.


Disclaimer: Starting from v8.0, some terms have been deprecated. Older releases will only use the deprecated terminology, and new releases will only use new terminology. Please see for a complete list of those changes, and in which minor versions it happened.
