[Pharo-project] extra class category added in Pharo-2.0 for Monticello package

When I load a Monticello package that was developed in Pharo-1.X, into a Pharo-2.0 image, I get an extra category created. For example, a package named "Some-Thing-author.n.mcz" originally contained class categories: Some-Thing-Model Some-Thing-View In the Pharo-2.0 system browser, I see an extra category, like: Some-Thing Some-Thing-Model Some-Thing-View I thought it was just an artifact of the new browser. However, when I do a diff, before saving the changes to a Monticello version, I see that the "Some-Thing" is flagged as diff. Will this extra class category cause any trouble, if I want to load the new Monticello version into a Pharo-1.4 image?
