Release notes provide you with information on new, changed,
and removed functionality (features). This particular release notes
document explains the major differences between HP-UX 9.0 and HP-UX
10.0. It also describes changes for HP-UX 10.01, 10.10, 10.20, and
10.30.
Release notes do not completely document all of the features
of a release. Instead, release notes contain high-level information
and provide pointers to more detailed operating system and product-specific
documentation.
Where appropriate, release notes also tell you about changes
in the support of products.
