The version of org-mode that came with my version of Emacs (24.5.2) is 8.2.10. I have installed version 8.3.1 from ELPA and added this to my init file:
(add-to-list 'load-path "~/.emacs.d/org-20150803")
(require 'org)
When I check the version of org in Emacs, it says:
Org-mode version 8.2.10 (release_8.2.10 @ /home/meir/.emacs.d/elpa/org-20150803/)
That is, it reports the old version and the new directory... (the built-in version is located in /usr/local/share/emacs/24.5/lisp/org)
Here is the relevant portion of my init file (there is nothing before this portion):
(require 'cl)
;; Org-mode that was shipped with Emacs
(setq load-path (remove-if (lambda (x) (string-match-p "org$" x)) load-path))
;; ELPA
(setq load-path (remove-if (lambda (x) (string-match-p "org-20" x)) load-path))
(add-to-list 'load-path "~/.emacs.d/org-20150803")
(require 'package)
(add-to-list 'package-archives
(package-initialize)
(require 'org)
How do I get Emacs to load the new version of org-mode?
