Versioning
}
This is version 1.0, and describes version 1 of the data
structures. All future
\textbf
{
compatible
}
releases of this
specification will be blessed 1.
\textit
{

}
, for some ever-increasing
version of
\textit
{
x
}
. A compatible specification is one that
explains better some unclear points (see ``Bugs'' above) or that adds
record types that may be identified (and possibly ignored) by previous
parsers.
If we ever need to release version 2 (or further) of the SDB
structures, the specification version will be raised accordingly. New
specifications will continue to describe older versions of the data
structures, and parsers running on host computers will be required to
still parse the older versions. (No such requirement is there for
soft-cores, because the parser code is synthesized together with the data
structures).
