Revision History displays the revision history of a post or page, with links 
to the content of each revision.
The revision history is appended to the <code>content</code> of the post or page.
The following are configuration settings which can be changed in the Revision 
History submenu of ‘Settings’.
<ol>
<li>Display on pages.</li>
<li>Display on posts.</li>
<li>Show autosave revisions.</li>
<li>Show the revision timestamp in the post title.</li>
</ol>
By default the revision history is not shown on any posts or pages.
For control over where you place the revision history use the <code>rh_the_revision</code> function. 
It takes optional parameters, before and after. For example:
<pre><code><?php rh_the_revision('<h4>', '</h4>'); ?>
</code></pre>

Keep your WordPress fast and your database clean!
WordPress 3.6 allows users to control how many revisions are stored for each supported post type. 
This plugin provides an interface for this new functionality.
<h4>Why you should use this plugin?</h4>
Each time you click Save Draft or Update, a revision is saved on the database. 
WordPress will store all revisions for each page on your blog. Revisions allow you to look back at the recent changes you’ve made and revert to an earlier version if necessary.
But, what about all those revisions that you won’t use anymore? Yes, they are still there, taking space from your hosting space and increasing the volume of your database and making it slower and heavier!
With this plugin you can easily limit the number of revisions that you want to save, with this you are saving space on your database and keeping the overall site performance in good shape.
<h4>How can I change/limit the number of revisions stored on my database?</h4>
Once <code>WP Revisions Limit</code> plugin is installed and activated, go to Settings > Revisions Limit in your WordPress site and specify the number of revisions you want to store for each post/page under Revisions Options section.
<h4>Compatibility:</h4>
This plugin is fully compatible with any WordPress site with version 3.6 or higher.
Requires at least WordPress 3.6 and PHP 5.3
