The Breeding Scheme Designer is a tool to explore trade offs between different evaluations strategies in breeding programs using stochastic simulation. Comparisons of different scenarios with respect to genetic gain and genetic gain per dollar invested are enabled.

- Now calculates heritability of multi-stage testing as if data from all stages were used to estimate means. This is best practice, although not standard in breeding pipelines.
- GxE variances as well as genetic variances are scaled to the inbreeding coefficient of the generation of line derivation. In the previous version, this was only done for the genetic variance.
- The calculation of selection differential has been simplified.
