The blurb about it from our 'NEWS' file:

*** issue 49: update contact email

    https://github.com/salewski/ads-github-tools/issues/49

    The old contact email address 'salewski@att.net' /should/ still work, but
    the preferred address to use going forward is 'ads@salewski.email'. Note
    that the author has experienced a fair amount of mail lossage this year
    (2020) due to overly-aggressive mail filtering by the AT&T mail system;
    lots of legit mail does not get through, and there is no indication of the
    blockage. For best results, use the new address.
