Single column text format and modernized font styles improves readability
QR Codes replace vertical margin sidebars and arrows to identify code changes more accurately
Shading for table headers and notes improves locating tables and applicable notes
Grouping of associated content brings tables and figures immediately after the parent section
Users have capability to validate authenticity of their book and register it with the ICC to receive incentives.
