<p>Unless post revisions are explicitly limited, WordPress will build up a hefty sum of revisions over time. While it’s great to have revision history for some recent content, the chances that old revisions will be necessary diminish the longer a post has been published. Revision Strike is designed to automatically remove these unneeded revisions on older, published posts.</p>
<h4>How does it work?</h4>
<p>First, a threshold is set, with a default of 30 days. Once a day, Revision Strike will run and find any post revisions in the database attached to published posts with a post date of at least 30 (or your custom threshold) days ago, and “strike” (tear-down and remove) them from the WordPress database.</p>

<p>Revision Diet is a plugin to limit the number of post revisions that are saved. It does exactly what you expect – it allows you to set a number of revisions to keep for each post and deletes any revisions beyond that number. This number will not include the autosave revisions.</p>
<p>The options page is extremely simple – enter the number of revisions to keep and save your options. There is also a button to ?Trim Excess Revisions.? This button will trim all the extra revisions from every post in your WordPress installation. (Using it is optional.) As for regular use, each time you save a post the oldest revisions on that post will be deleted from the database down to the limit that is currently set.</p>
