Hi all, "Org contrib" refers to the list of Emacs lisp files that you find in the contrib/ directory of Org's repository:
https://code.orgmode.org/bzg/org-mode/src/master/contrib The idea of this directory was to have a place where to promote Org packages even if they are not part of Org's core (ie the files that go into Emacs core.) It was also useful as a place to welcome packages from authors who don't sign the FSF copyright assignment. Both reasons are kind of obsolete nowadays: many, if not most useful Org contributions are published elsewhere. Also, mixing authors who signed the FSF assignment and those who don't is never a good idea for a repo, even if the contributions happen in separate spaces. Org 9.5 will ship without the packages in the contrib/ directory. Emacs lisp files in contrib/ will be packaged as an Org ELPA package that you can install independentely from there. The files will live in a new org-contrib.git repo on code.orgmode.org. In the long run, every Emacs file in org-contrib.git need to find a proper maintainer (who will decide where to maintain it) or to be listed in the list of Emacs orphan packages. If you use Org contrib/ files from git, you will have to clone a new repository when the split is done, within the next weeks. If you use org-plus-contrib, you don't have anything to do before Org 9.5 is released. When it is, you will have add Org ELPA to your configuration and install org-contrib from there. If you have any question on this, please let me know! Best, -- Bastien
