Customers will discover over a dozen enhancements across the product, such as native support for Apple M1, powerful new heuristics for non-convex quadratic models, norm constraints, deterministic work measures, memory limit parameters, and more user control of IIS computation, as well as improvements to callbacks and tuning.
