- Unexpected crashes that occur upon XML input have been resolved.
Version 3.1.15
Release date: May 30, 2007
This version is the first public release of NAADSM 3.1. NAADSM 3.1 preserves compatibility with NAADSM 3.0, but introduces several new conceptual features and numerous enhancements.
NAADSM 3.1.15 follows version 1.1.0 of the model specification: no further substantial changes will be made to the specification for the 3.1.x development branch of NAADSM.
Bugs fixed:
- Accuracy of distance calculations for vaccination and destruction ring radii is improved.
- Accuracy of distance calculations for direct and indirect contact is improved.
New features:
