We just published a new poster at EICC'22 that covers a brief history of hiding patterns since their emergence around 2014. The paper is available through its DOI (10.1145/3528580.3532997) and the poster is available here: https://wendzel.de/dr.org/files/Papers/EICC22_poster.pdf.
Update (Jul-06-2022): the poster was updated to additionally cover the most recent paper on patterns (see latest blog post).
