For all other comics at https://www.collectedcurios.com/ no new strips were released since 2020.
_{I.e., besides SequentialArt only occasionally a new Curious Transmission is released there.}

ToDo: Analyse web-page, evaluate a extraction statement and ultimately pose a PR adding SequentialArt to DailyComics.
