* Text group support was added to the MaxiCode symbology.
4+
* A new physspec option was added to simplify the generation of vector symbols with specification-compliant physical dimensions.
5+
* Nominal and bounding metrics can be looked up in per-symbology application specific tables with the new ast option.
6+
* In physspec mode the gridfit option validates the effective X-dimension against specification bounds, trying alternate rounding directions when the initial snap falls outside the allowed range.
