The NASM 2 series supports x86-64, and is the production version of NASM
since 2007.
\S{cl-2.15.01} Version 2.15.01
\b Fix building the documentation from the release archive. For 2.15,
the user has to do \c{make warnings} manually in the main directory in
order to be able to build the documentation, which means Perl needs to
be installed on the system.
\b Add instructions for Intel Control Flow Enforcement Technology (CET).

For example, to turn on the \c{d} and \c{m} flags but disable the
\c{s} flag:
\c %pragma list options +dm -s
For forward compatility reasons, an undefined flag will be
ignored. Thus, a new flag introduced in a newer version of NASM can be
specified without breaking older versions. Listing flags will always
be a single alphanumeric character and are case sensitive.
