[O] Missing contrib packages

[Francesco Pizzolante]

Hi,

I have Org-mode version 8.2.4 (8.2.4-8-gf1b933-elpaplus @
c:/Users/fpz/Documents/home/.emacs.d/elpa/org-plus-contrib-20131216/).

I notice that I miss several packages like htmlize (important) and
org-effectiveness.

My questions are:

- why, in the org-plus-contrib from elpa, I miss these packages (present
  in the master branch)?

- why, in the release version 8.2.4 downloaded from http://orgmode.org/,
  I have htmlize but not org-effectiveness?

Thanks a lot,
 Francesco
