My mistake. I can wait longer between revisions. I was just trying to include Tom's feedback promptly, I didn't think having many versions would be an issue. Between V1 and V3: I have fixed a lot of style issues Tom identified. Added documentation to the SEV documentation file. Fixed some incorrect type usage. Made the logging more uniform. Removed writing on the SHUTDOWN command. And fixed some error handling.
