Hi, There are two bugs introduced in commit 6efb073463481ee572eb3bb1155cc3b0d6987df6; I Cced Daniel, the commit author. It persists on main. Since the bugs are intimately related to ob-clojure and the org mode source blocks, I've just attached an org file that highlights the two bugs, I think that's easiest. I'm fairly sure that they have the same root cause: wrapping each block inside `(binding [*out (java.io.StringWriter.)])'. I'm not too familiar with (ob-)clojure, so I'm not sure what the best way to solve this would be, but I'm happy to try if necessary. Best, Rens
