- Automatic reformulation framework
- Logical, combinatorial and conic constraints are reformulated into basic constructs suitable for a given solver, see https://mp.ampl.com/
- Out-multiplication of quadratics, as typical for MIQP solvers
- Piecewise-linear approximation of univariate nonlinear functions
- 9 MILP/MIQP solvers implemented in MP, they are now default AMPL binaries
- Multi-objective emulator #239
- Reformulation explorer #232
- Automatic solution check #200
- NL Writer library added in C/C++ and Python #30
- Expression tree output, suitable for (MI)NLP solver API, added in #137
