OpenVMS Version 7.2 does not maintain the structures to support MAC (mandatory access checking)
in a level B1 security environment.

Security information within this cell is not backward compatible because the JIB is shared among all
processes in a job tree.
6.21.2 Privileged Code Changes at Version 7.0
V7.0
Privileged-code applications that were recompiled and relinked to run on
OpenVMS Alpha Version 7.0 do not require source-code changes and do not
have to be recompiled and relinked to run on OpenVMS Alpha Version 7.1 and
later.
Privileged-code applications from releases prior to OpenVMS Alpha Version 7.0
that were not recompiled and relinked for OpenVMS Alpha Version 7.0 must be
recompiled and relinked to run on OpenVMS Alpha Version 7.1 and later.
OpenVMS Alpha Version 7.0 included significant changes to OpenVMS Alpha
privileged interfaces and data structures. As a result of these changes, privileged-
code applications from releases prior to OpenVMS Alpha Version 7.0 may require
source-code changes to run correctly on OpenVMS Alpha Version 7.0 and later.
For more details about OpenVMS Alpha Version 7.0 changes that may require
source changes to privileged-code applications, refer to the OpenVMS Alpha
Guide to Upgrading Privileged-Code Applications.
For information about recompiling and relinking device drivers, see Chapter 7.
