The updated MCHW will look and feel quite different with its new structure and new style. In addition to these overarching changes, there have also been some updates to technical requirements made to specific documents. These may be difficult to spot because of the new layout and design, so this page highlights the key technical changes for each MCHW document.

This information is provided as assistive only and may not be complete. The revised MCHW documents should be read to confirm the full extent of the technical changes and how they apply to particular work aspects. All liability for the use and interpretation of this information remains solely with the user.
