+.Ss Upgrade path to NetBSD 1.5.1
+If you are not installing your system ``from scratch'' but instead
+are going to upgrade an existing system already running
+.Nx
+you need to know which versions you can upgrade with
+.Nx
+1.5.1.
+.Pp
+.Nx
+1.5.1 is an upgrade of
+.Nx
+1.5 and earlier major and patch releases of
+.Nx .
+.Pp
+The intermediate development versions of code available on the main trunk
+in our CVS repository (also known as ``NetBSD-current'') from
+.Em after
+the point where the release cycle for 1.5 was started are designated
+by version identifiers such as 1.5A, 1.5B, etc.
+These identifisers do not designate releases, but indicate major changes
+in internal kernel APIs.
+Note that the kernel from
+.Nx
+1.5.1 can
+.Em not
+be used to upgrade a system running one of those intermediate development
+versions.
+Trying to use the
+.Nx
+1.5.1 kernel on such a system
+.Em will
+probably result in problems.
+.Pp
+Please also note that it is not possible to do a direct ``version''
+comparison between any of the intermediate development versions mentioned
+above and 1.5.1 to determine if a given feature is present or absent
+in 1.5.1.  The development of 1.5 and the subsequent ``point'' releases
+is done on a separate branch in the CVS repository which was created when
+the release cycle for 1.5 was started, and during the release cycle of
+1.5 and its patch releases, selective fixes and enhancements have been
+imported from the main development trunk.
+So there are features in 1.5.1 which were not in e.g. 1.5B, but the
+reverse is most probably also true.
+.Ss Major Changes Between 1.5 and 1.5.1
+The complete list of changes between
+.Nx
+1.5 and 1.5.1 can be found in the file CHANGES-1.5.1 in the top directory
+of the source tree.
