Does anybody know if there is a change in the default underlying model in Alfresco? If I copy the aspects I made in Alfresco 2.1 (custom-model.xml, web-client-config-custom.xml etc.), then they cause errors in Alfresco 3, while they work fine in version 2.x.
I have the same problem. Is there any other way to make a custom model, e.g. declaring new metadata for documents, than changing XML in the extension folder?
