Not sure if this is a cljdoc issue or not, but I noticed that the latest https://cljdoc.org/d/seancorfield/next.jdbc docs are for version 1.2.659 which came out in 2021 (the latest is https://github.com/seancorfield/next-jdbc/releases/tag/v1.3.1093).
You're looking at the wrong URL -- that's the old group/artifact. https://cljdoc.org/d/com.github.seancorfield/next.jdbc/1.3.1093/doc/readme is what you want.
Thanks for the quick reply... A Google search jdbc.next gives old links for both cljdoc and clojars on the first page (the correct versions show on the second).
Luckily, even on that old README, it shows a cljdoc button linking to the correct, newer group/artifact/version:
(and it shows the newer Clojars group/artifact/version too)
