Automatic Updater installs WordPress updates automatically
One of your tasks as a WordPress admin is to update the blog software, themes or plugins whenever updates become available. Here it is essential to be fast if the update fixes security vulnerabilities or stability issues. You can however only be fast if you are aware of an update. WordPress displays available updates in the admin dashboard, which is probably the most common way of receiving word about WordPress, theme or plugin updates.
The time it takes to install the update can be problematic if a known vulnerability or issue is fixed by the update. Say you are going on a trip for some time with no option to access your blog to update it in that time. Another possible scenario is an update that gets released when you are sleeping, so that you only get to know about it the next morning.
Automatic Updater is a WordPress plugin that resolves this by installing updates automatically when they get released. This only works if file permissions are set correctly so that files can be updated via the WordPress web interface / the plugin.
The main benefit here is that updates get installed as soon as they are released, reducing the time between updates significantly. It needs to be noted though that this only works if you do not test updates before they get installed on a live system, and that you can very well run into a situation where an automatically installed update causes a issue on the blog.
If you are unlikely to be affected by this, for instance because you are running standard WordPress with the default theme, then it is unlikely that you may experience any issues ussing the add-on to update the blog and its files automatically. I would not recommend using the automatic update plugin on important sites, but on sites that are smaller or less important, it is a solid option to reduce the time it takes to update and reduce the time it takes to administrate the blog.
