The Developer's Toolkit (NDT) has also received a quick overhaul and now supports field groups. If you don't know NDT already, you should look to the NDT if you are looking for a Source Analysis tool or a Compare and Merge tool. It is recommended that you use version NDT_v3.00.400 if you are using it in connection with Microsoft Dynamics NAV 2009.

Finally we have released the Language Modules for 12 Languages (AU, NZ, DE, DK, ES, FR, GB, IE, IN, IT, NA and NL). If you are not familiar with Language Modules, they enable you to add additional language(s) to an installation. This is particular useful in multicultural companies, e.g. a German installation with German and Italian speaking employees. Please read the instructions carefully and note that the Language Modules for Microsoft Dynamics NAV 2009 require the Page ID Hotfix to be installed first.
