Five (six) UAP observables in the Schumer/Rounds amendment

Hello all!

I was reading the lastest version of the Schumer/Rounds S.2226 NDAA amendment and it struck me, that the in the earlier versions of this act there were five UAP observables mentioned:

(i) Instantaneous acceleration absent apparent inertia.
(ii) Hypersonic velocity absent a thermal signature and sonic shockwave.
(iii) Transmedium (such as space-to-ground and air-to-undersea) travel.
(iv) Positive lift contrary to known aerodynamic principles.
(v) Multispectral signature control.

But now there is a sixth observable added:

(vi) Physical or invasive biological effects to close observers and the environment.

Is this a totally new thing in the amendment or it was added somewhere earlier, that I apparently missed?
