WordPress 3.6 allows users to control how many revisions are stored for each supported post type. No longer must you rely on the <code>WP_POST_REVISIONS</code> constant, which applied universally. This plugin provides an interface for this new functionality.
With this plugin enabled, simply visit Settings > Writing to specify the number of revisions retained for each post type.
Why is this helpful? Revisions are stored in the database, and if many are stored, can cause bloat. This bloat may lead to slower queries, which can have a noticeable performance impact. The value of these revisions also depends on what is being tracked. For example, I may want to store every revision of the posts I write, but only desire to keep the latest five versions of each page on my site. Starting in WordPress 3.6, this control is available. WordPress doesn’t provide a native interface to specify revisions quantities, so I wrote this quick plugin to do so.
Thanks to Maria Ramos at <a href="http://www.webhostinghub.com/" rel="nofollow ugc">WebHostingHub</a>, the plugin is also available in Spanish. Many thanks to her for her efforts!
Development is at https://git.ethitter.com/wp-plugins/wp-revisions-control.

It does not take up much space in the backend Wordpress console so it can always be left activated.
