I'm looking for a better way to compare CY2018 reporting year EH eCQM specifications with those for CY2019, which are in CQL.  Is there a resource that has the CY2018 specs in CQL format, to make the comparison with CY2019 simpler?

For example, I can fairly easily compare CY2019 and CY2020 ExclusiveBreastMilkFeeding*.cql files to identify differences (such as Value Set changes for Estimated Gestational Age at Birth and Neonatal Intensive Care Unit, or logic changes in "define" statements).

For a different kind of example, I found on the qualityreportingcenter.com site a PDF (named "ecqm_slides_qrda-ig-changes-for-cy-2019_20190327_vfinal508.pdf") that details the QRDA changes between reporting years 2018 and 2019 in side-by-side comparisons.

Is there a similar resource to above examples that compares the eCQM specifications using same definition format (CQL) between both years?

Thank you.
