CRSP has always had a short waiting period, they did not change it.
They did lower the free float rule
Free float rule was pretty low already for ftse, yea? Like we went through this with aramco still has free float under 3%, yet it's in vxus.
CRSP did change their rule earlier in Feb, where they added a clause that later allowed SPCX to be included, despite having <10% float. The clause allowed SPCX to be included because of its market cap. The timing is also suspicious.
