@ -135,6 +135,22 @@ New Functionality
- The QUIC analyzer has been extended to support analyzing QUIC Version 2
INITIAL packets (RFC 9369).
- Conditional directives (``@if``, ``@ifdef``, ``@ifndef``, ``@else`` and
``@endif``) can now be placed within a record's definition to conditionally
define or extend a record type's fields.
type r: record {
c: count;
@if ( cond )
d: double;
@else
d: count;
@endif
};
Note that generally you should prefer record extension in conditionally loaded
scripts rather than using conditional directives in the original record definition.
