  note: >-
    The developer changelog has a live RSS feed and ten entries spanning 2022-02-04 to 2023-03-27,
    and nothing since. Postscript has shipped RCS, Shopper and a whole Postscript AI product line in
    the meantime, all announced on the marketing site and none of it reflected here. The changelog is
    present and machine-readable but no longer current, which is a different failure from not having
    one — an integrator polling this feed would conclude the API is frozen.
