That's out of our control. htmlize is not strictly required. But without htmlize, code in the code blocks is not colored. Note that what is now a warning used to be a message. Now, it is more visible, which was the reason why this was promoted to warning. > In any case I have "fixed" this removing the language from #+BEGIN_SRC. > For example: > > -#+BEGIN_SRC sh > +#+BEGIN_SRC > > which for me is enough. You can also: 1. Suppress the warning 2. Set `org-html-htmlize-output-type' to nil to tell Org not to try coloring -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at <https://orgmode.org/>.
