Technically, the current Emacs version is Emacs 27. So, following our maintenance convention [1], we should support everything down to Emacs 25 (e.g. 27-2). However, Emacs 28 is going to be out soon-ish and the problem is not on bugfix branch, but only on main. I am not sure if we need to follow version-2 convention for main as well. Maybe better require only version-1? Weaker back-compatibility requirement can allow us to implement more advanced features relying on more recent Emacs versions. [1] https://orgmode.org/worg/org-maintenance.html Also, org-src.el from bugfix may not run on Emacs 25: In end of data: org-src.el:1312:1:Warning: the function ‘replace-buffer-contents’ is not known to be defined.
