-    - latex_printer: print Pyomo models to a LaTeX compatible format
-    - contrib.solver: preview of redesigned solver interfaces
-    - simplification: simplify Pyomo expressions
- - New solver interfaces
-    - MAiNGO: Mixed-integer nonlinear global optimization
- - ...and of course numerous minor bug fixes and performance enhancements
