6.4.2.13.
Products installing workflows may need to add permissions
Up one level
The new "Editor" (aka. "Can Edit" on the Sharing page) in Plone 3.0 makes it easy to let people collaborate on content authoring. In some cases, editing also means the ability to add new objects inside the object people are editing.
For this to work, third party content types that add custom workflows will have to either use one of the standard "add content" permissions or explicitly give Editor the Add portal content role.
See Ticket #6265 for the changeset and full explanation.
