CORBA3 — CORBA components requires new GIOP version?

Please forgive me if this is old news. I was trying to find a recent
CORBA Components spec to see what changes it has had on the core spec.

It looks like several new TypeCode kinds have been added (two from
CCM?), but doesn't that require a new GIOP version? Even if the specs
did declare the wire formats in new versions of Chapter 15, how could
older GIOP 1.2 ORBs handle them?

Specs:

CCM FTF drafts of modified CORBA Core chapters
Adds tk_component and tk_home in 10.7.1. No update to 15.

CORBA 2.4.2 complete specification
Adds tk_local_interface in 10.7.1. No update to 15.

close no change, see above
