Code Commander Gisbert Avellan has just updated the community version of Object Manager to work with db4o v7.4 (download, source code). This is a limited update since it only works with databases generated from Java. It's important to note that OM Community (db4o-om) is not the same as OME (Object Manager Enterprise) which is inside your db4o installation (in the ome folder). Both are free software now but OME is the official db4o object browser while OM is maintained by the db4o community. For a comparison of both tools see this page. Thanks Gishac!!!
