In particular (comparing the org-plus-contrib-20150202 package against today's http://orgmode.org/cgit.cgi/org-mode.git/tree/contrib/lisp):

htmlize.el

ob-stata.el

org-colview-xemacs.el (not that I really care about this one)

org-download.el

org-ebib.el

org-effectiveness.el

org-eldoc.el

org-eww.el

org-index.el

org-license.el

org-passwords.el

orgtbl-sqlinsert.el

ox-extra.el

ox-gfm.el

At the very least, please ensure that htmlize.el gets packaged.
