Achilles v1.2.2 has been deployed on github. You can review the release notes here:
There are several community contributions for bugfixes in this release, as well as a new flag to optionally run the cost analysis (because the latest 5.0.1 CDM schema has switched the cost table, you should only set the runCostAnalysis flag to TRUE if you are working on the 5.0 schema, and not the 5.0.1 schema).
In addition, this release depends on the latest version of SqlRender. Please ensure you completely remove and reinstall SqlRender prior to executing the latest Achilles build.
