- new `estimated_params_remove` block to remove estimated parameters (preprocessor@5ffbc5bad31c306f561d673cde36d460cb5906c1)
- When `use_dll` option of the `model` block is set, the preprocessor now takes advantage of parallelization when compiling the MEX files (preprocessor@f6053df7545174885486a457a2253897a1ed4e27, preprocessor@5cf4729ab0790084af0b0a9e9a1062ddefff3401, preprocessor@dd66459e5f2e5c57ea25cb4a0e8709b22ff3195b, preprocessor@3dd40c6c42d82997972e90899da8632a747f5c90)
- New options `periods` and `drop` to `evaluate_planner_objective` (!1967)
- Support for new mathematical primitives: complementary error function (`erfc`), hyperbolic functions (`cosh`, `sinh`, `tanh`, `acosh`, `asinh`, `atanh`) (preprocessor#85, preprocessor@c0ea8d72038cd6c57e48aca26d2d29866848ae0a)
