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.

Post revisions are backups of articles editors are writing and forgot to hit save. They are also article versions stored in the WP database, as a way to see how the post’s content evolved.
While they are important for this later reason, sometimes WordPress creates post revisions with minimal changes to the post content. These are “redundant” post revisions and they do nothing more but slow down page loading time and bulk up the database with useless content.
This WordPress plugin can help webmasters delete these kind of redundant posts.
