I originally ran the audit on 3/27 (IIRC), and then ran it a few additional times as I fixed data quality issues in my scripts (the ones linked in the post). The last time I ran it was on 5/19-5/20, when I was finalizing the post. You can also see that I did a new release of `pgpkeydump` at around the same time, to add some more extracted datapoints.

PyPI's admins have been wanting to remove PGP support for years; all I did was provide the final nudge.
