"artful"

Changes for Ubuntu 17.04
------------------------
https://wordpress.org/news/2017/04/wordpress-4-7-4/
https://wordpress.org/news/2017/05/wordpress-4-7-5/

https://codex.wordpress.org/Version_4.7.4
https://codex.wordpress.org/Version_4.7.5

You can change the codex URL to a different version number if you really
want to see all the individual security fixes.

Testing Done
------------

Regression Potential
--------------------
WordPress maintains separate branches to backport security fixes. I suspect 
that the older the branch gets, the more likely it is that something will break.

WordPress still uses trac/svn, but there's this handy read-only copy
that is easier to examine:

Other Info
----------
On one hand, I hope right now no one actually uses the Ubuntu package on a live 
web server. I mean, if they are using the development version of Ubuntu, it 
might actually work but otherwise, it's not really received any security 
support at all.

Similarly, I guess there's a concern that if we start providing security
updates, then people will start thinking that Ubuntu's 'wordpress'
package is safe to use, which is fine as long as someone from the
community will indeed package these updates from now on. Otherwise,
maybe doing these security updates is not really helping anyone?

Since 14.04's wordpress is in unseeded universe after 3 years, it's not
supported any more, but since WordPress still provided a release for it,
I figure it's not that much extra effort to do that update too.
