Release Notes for Version 11.0

In addition to performance enhancements, Gurobi 11.0 adds the following new features:

Mixed-Integer Non-Linear Programming (MINLP) Problems: Gurobi 11 offers solving non-linear models using spatial branch-and-bound and outer approximation as an alternative to the static piecewise-linear approximation of non-linear constraints supported in earlier versions. See the discussion of function constraints with dynamic piecewise-linear approximation for more information.
Default behavior of NonConvex parameter changed: now, in default settings, Gurobi will solve models with non-convex quadratic constraints.
Models can now be copied between environments.
Better control over the concurrent LP optimizer with ConcurrentMethod.
New parameters:
- SolutionTarget to specify the solution target for LP.
- TuneDynamicJobs to allow distributed tuning using a dynamic set of workers.
- TuneUseFilename to use the file name instead of the model name.
- MixingCuts to control the generation of Mixing Cuts.
Numerous changes to gurobipy:
- Installation and packaging changes.
- New classes, methods and properties.
- Other enhancements.

Please refer to the Detailed Release Notes for more details, including supported platforms and code conversion notes. All bug fixes listed by version can be found on our website.
