From the comment section:
Mark and find your favorite things and locations in org easily: Create
and update a lookup table of your references and links. Often used
entries bubble to the top and entering some keywords displays only the
matching entries. That way the right entry one can be picked easily.
References are essentially small numbers (e.g. "R237" or "-455-"),
which are created by this package; they are well suited to be used
outside of org. Links are just normal org-mode links.
* org.el (org-modules): Do not include org-mew.el, org-vm.el,
org-w3m.el, org-wl.el as these files are now part of contrib/.
* org-w3m.el:
* org-vm.el:
* org-w3m.el:
* org-wl.el: Move to contrib/.
The purpose behind this change is to prepare a future split between
org-mode.git and org-contrib.git: org-mode.git will contain all files
that are directly relevant to GNU Emacs, while org-contrib.git will
contain files that are more peripheral and/or from authors who cannot
assign their copyright to the FSF.
This is *not* a way do downgrade those files, it is a way to prepare
org-contrib.org so that it gets more attention and more contributors,
thanks to the fact that there is no legal barrier to contribute to it.
* contrib/lisp/org-contacts.el: Add defvar for date. Similar to org.el.
(org-contacts-anniversaries): Setting date to nil breaks the
function. Bug was introduced in e4cebbe40.

# the commit.

with ox-s5.
(org-deck-toc): Use HTML_CONTAINER_CLASS instead of html-container-class.

Remove `completion-in-region--postch' from `post-command-hook'
because it doesn't (seem?) do anything really useful.
* org-contacts.el: Improve the completion part:
- When a group is found, it now replaces the name of the group by the
addresses of the member of the group rather than appending the
addresses.
- One can now complete on all part of an address and not only on the
beginning of the name.

...))
* contrib/lisp/org-e-latex.el: Replaced a set of \begin{center}

(org-export-as): Use new function.
* lisp/org.el (org-macro-expand, org-macro-replace-all): Change
signature. The function now accepts an alist of templates so it
doesn't have to rely only on `org-macro-templates'.
(org-macro-initialize-templates): {{{date}}} is not anymore an alias
for {{{time}}}. During export, it will provide the value stored in
DATE keyword instead.
* testing/lisp/test-org-export.el: Add tests.
* testing/lisp/test-org.el: Update tests.
* contrib/lisp/org-export.el (org-export-expand-include-keyword): Use
new functions to comma escape contents of included files when in an
example or a src block.
