WP Revisions Manager

It helps you keep a clean database by removing unnecessary posts revisions. It lets you delete specific posts revisions.
Perfectly integrated in the WordPress back-end, and uses wordpress core functions to safely delete revisions.
You can also limit the number of revisions to be stored.

How does it work?

The plugin adds a discreet link next to the default revisions counter (see screen-shots section).
When you click on it, it will purge the appropriate post revisions via AJAX.
It also add a new bulk action option in the post/page row view to let you purge revisions of multiple posts at once.

NOTE: Works only for the post_types that supports ‘revisions’
