What's in This Document?

HP-UX 11i Release Notes contains information about the release of HP-UX 11i as of December 2001. It applies only to features that are included in the HP-UX operating system or one of the five Operating Environments (discussed later in this chapter under “What's HP-UX 11i?”).

In addition to changes made since the initial release of HP-UX 11i, this document includes information on changes to HP-UX that occurred after the last major system release, HP-UX 11.0, and which have been incorporated in HP-UX 11i. These latter changes were made as part of less comprehensive releases known as Extension Pack releases (for servers) and ACE (Additional Core Enhancements) releases (for servers and workstations). If your organization received one or more of these releases, then you may already be familiar with some of the information. (If, on the other hand, your organization did not receive any of the Extension Pack or ACE releases, then all of the information in this document will be new to you.)

Additional product-specific release notes files are located in the /opt directory, in sub-directories named /opt/product_name/newconfig/RelNotes (where product_name represents the name of the product for which those release notes apply). (For example, Distributed Computing Environment [DCE] release notes are located in the /opt/dce/newconfig/RelNotes directory.)
