[Zope] Versioned connectors from ZODB

If I get a versioned connection from the ZODB: conn = Zope.DB.open(version="myVersion") root = conn.root() app = root['Application'] # do some stuff get_transaction().commit() conn.close() Are the changes now in a version? How do I get those changes rolled into the "trunk" version of the ZODB? I guess all objects changed in the version will now be "locked" to that version until I apply the version changes to the trunk? Thanks Etienne
