The formation of the Zope Toolkit was facilitated by the Zope Toolkit Steering Group. It was influential in defining the scope of the ZTK and establishing community practices and policies around it.
In early 2010 the steering group members stepped down, after succeeding in the creation of the toolkit concept and getting wide community support for it.
After the steering group members stepped down, the Zope community agreed on the formation of the release team (Release team) with a much narrower focus around release management of the ZTK.
