As its default behavior, WordPress always makes a new revision when you save your post. This is too often even if you like revision control. Thin Out Revisions (TOR), a plugin for WordPress, will help you thin out revisions and more. (Japanese readers may prefer this post.)
TOR has three powerful features.
Thinning out revisions – Getting ready for WordPress 3.6
Thin Out Revisions 1.3 is fully compatible with the new revision screen in WordPress 3.6. You can remove intermediate revisions during comparing in ‘compare two revisions’ mode. To do it, simply press ‘Thin Out’ button.

You can also remove each revisions except current one in Edit Post screen.
These features are available from WordPress 3.6 & TOR 1.3. if you run TOR in WordPress prior to 3.6, see this page.Disabling unnecessary revisioning
TOR has a feature to stop making unnecessary revisions if you enable the feature.
- Delete revisions on initial publication
To use this, go to the ‘Settings’ – ‘Thin Out Revisions’ admin page and turn it on.

Revision Memo
The Revision Memo feature enables you to put a short text note on revisions. You can see memos in Edit Post (Edit Page) screen like below.

Make sure that you check the ‘Revision Memo’ screen option in Edit Post (Edit Page) screen.
And more…
You can install TOR in a standard manner. Search it on your admin page. Please also check the FAQ page in WordPress.org especially when you use the ‘delete on initial publication’ feature. If you have any comments, leave them in the WordPress.org support forum
In addition, TOR works fine in multisite environment. Why don’t you download it today?
