Version 2.20
2022-09-15
Summary
Large performance improvements during simulation due to less aggressive garbage collection. Benchmarks can be found on the Version benchmarking page. Updated to latest version of Zimpl and LpSolve for faster optimization. Added support for Gurobi 9.5. New importer for data exported from harvester simulator (Oryx). Numerous bug fixes.
New Features

Changes
- Carbon and nitrogen from the spinup period are now grouped into the initial stock. Net input is carbon and nitrogen from decomposition of plant material accumulated since the simulation start.
- Support for version of Gurobi older than 9+ has been removed. This follows Gurobi's list of supported versions.
- Support for version 10.0 of Gurobi has been added.
- Rudimentary support for CPLEX 22.10 has been added. There is limited support for CPLEX's return status and other versions of CPLEX.
- The open source solver LpSolve have been replaced by COIN-OR's CLP/CBC solver.
Bug Fixes
- Carbon content in above-ground biomass is now calculated from the table in Carbon sequestration
- Fixed an issue where users could not select folders in file dialogs.
- Fixed an issue when splitting a NC-area where the vertices of areas would overlap.
