I have not read of any approved changes to the laws recently.
Many CRSC recipients receive their full retirement pay as CRSC (generally with a 100% CRSC percentage). They have regular retirements. The same is true for CRDP, except 100% is not required. CRDP itself is retired pay.
You might be speaking about Chapter 61 retirees. None of the recent (last couple of years) proposed CRSC/CRDP changes have passed both the House and Senate...to my knowledge.
