Org-mode compilation fails with the following errors if emacs-25.2.2 is
used (Ubuntu-18.04 LTS bionic)

org.el in the main branch still declares

but it seems xdg.el used by org-persist.el was added in emacs-26.0.
I do not actually use emacs-25.2, but it happened that I have a test
container for Org based on Ubuntu-18.04.
Either org-persist and org-compat should be updated with some
compatibility code or required emacs version should be updated once more.

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.

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.
Best,
