You completely have the possibility to limit and delete the post revisions feature. However, we strongly recommend that you should not disable this feature because post revisions are really valuable in a lot of situations.

For example, we want to limit the number of revisions to 10. You can replace 10 with the number of revisions you want.

define( 'WP_POST_REVISIONS', 10 );
