At this point in the release cycle, we are working to get to a stable draft and are looking to address errors and bugs only. Other issues can be queued up for the next release. The final release of NIEM 5.0 is scheduled to be published this fall. At that time, 5.0 XML schemas and documentation will be published along with updates to NIEM specifications and tools.
