- Add `var_names(::GradTransform, [...])` and `all_names` for generating symbolic subgradient variables - Fix inversion operation in division when lower and upper bounds are the same - Add more support for higher variable indices - Add error for `binarize!` to assist in debugging - Add `split_div::Bool` argument to `factor`, which determines whether terms like `x/y` will remain as-is or get factored into `x * (1/y)` - Improve variable sorting so that, e.g., `x10` will not come before `x2` - Add `extract`, which can pull a subexpression out of a primal trace and substitute out auxiliary variables - Fix `fgen` bug that would use an incorrect subgradient variable
- Tests for division operations removed for `fgen`. Rules were written to match McCormick.jl, which was modified after this issue: PSORLab/McCormick.jl#69. This change only affects division by a negative McCormick object when the convex and concave relaxation values are not the same, but since `fgen` will be deprecated in v0.5, this issue in `fgen` is not planned to be fixed.
