Make it explicit that "improvements" is not meant to limit what kinds
of modified versions you can release. State in the table that you
must be able to release modified versions, not just the changes.
The right to merge in existing modules refers to those
that are suitably licensed.
Explicitly state the conclusion of the point about export controls.
