My Emacs ships with an older version Org-mode! How do I upgrade?
Org-mode develops quickly, which means that versions of Org-mode shipped with Emacs are more or less out-of-date. If you’d like to upgrade to the most recent version of org-mode, you have a number of options. • Download the most recent release of org-mode as zip or tarball and follow the installation instructions in the manual. • Clone and install the development git repository as explained here. If you don’t want to run the bleeding edge, you can still use git to track the most recent stable releases. • Install and updated org-mode automatically through the Emacs Package Manager as explained in this FAQ.
