Problem:
Often users that don't follow media or the forum have no idea there has been a new release or don't watch the rss ticker or have it disabled. So they keep running that version for years.

Solution:
Add similar pop-up like openelec as to notify users there's a new version available.
Like if they are running stable version tell them there's a new major or bug-fix release. For users running monthly build tell them of the new one or in case next one is stable we tell them that.
Redirect them to the website for more information on upgrading.
This keeps user base up to date with latest versions and we hopefully don't have to deal with people that are still using old builds (some of course do by choice). This will also provide better feedback on our latest releases because hopefully more people use it.
Many software packages have a similar notification.
Just show it once with the option to remind in xx days or suppress until next release.


Release Edit:
Add-on has been added to official XBMC repo and can be installed manually if you are not using 13.0 Gotham alpha2 or later builds.
