Nothing big, but some useful stuff. Income and DTI can officially be negative (and rate spread which I think everybody already knew).
There are also some useful new edits most likely based on what was found in the 2018 data. The county/state disconnect was taken from quality to validity. No CLTV edit for non-conventional loans. Missplaced decimal checks in the ratio fields.
I feel like they could have probably made some more quality edits, but I like the ones they did make.
