Hello Rostyslav,
Our checklist is based on IEC 62443-2-1 Draft 7 Edit 1 which was issued in June 2014. At the time when created the checklist, we thought that version was close to complete so we went with it. Unfortunately, that version of the standard has run into stumbling blocks and is still not approved.
Our intent is to update the checklist when the new version of IEC 62443-2-1 released, rather than downgrading to the 2010 release.
