Revision Moderation | drupal.org

The Revision Moderation module allows you to leave existing revisions of a node published while new revisions go into moderation for an administrator to approve.
Drupal 6

There is now an alpha release for Drupal 6. It should be working pretty well, but it it is an alpha due to several factors:

• There are still a few known bugs that need to be dealt with.
• No Views integration yet.
• The upgrade path for related modules/code hasn't been looked at or documented. (That is, Revision Moderation itself is fine but Actions, Views and WorkflowNG have all changed.)

If folks can grab the alpha, report bugs and help with the remaining tasks, particularly getting Views integration done, then an official release will come much faster.

Once we have a 6.x-1.0 stable out, we can focus on feature requests. Any new features will go into HEAD for a 6.x-2.x version.
