In the "Incompatible changes section", please change the section on org-mac-link to read as follows so that it incorporates further instructions on how to deal with the change:
*** Combine org-mac-message.el and org-mac-link-grabber into org-mac-link.el
Please remove calls to =(require 'org-mac-message)= and =(require
'org-mac-link-grabber)= in your =.emacs= initialization file. All you
need now is =(require 'org-mac-link)=.
Additionally, replace any calls to 'ogml-grab-link to 'org-mac-grab-link. For
example, replace this line:
(define-key org-mode-map (kbd "C-c g") 'omgl-grab-link)
with this:
(define-key org-mode-map (kbd "C-c g") 'org-mac-grab-link)
