Published Revisions Only disables revisioning prior to a post being published. Autosaves and revisions made after publication are stored.
It's quite possible that this plugin will not play nice with other plugins that modify WordPress' revisioning. I've had no problem with GD Press Tools, but other than that I don't know. Please report any conflicts to me. I'll list incompatible plugins here.
The best place to leave comments or issues is at the plugin site: http://www.kingrat.us/plugins/published-revisions-only
I do not monitor the WordPress.org support forums, so any problems left there are likely to have untimely responses.
