- convert reduce-args to a simplifier. Currently exposed as reduce-args2 tactic until the old tactic code gets removed. - bug fixes in model_reconstruction trail - allow multiple defs to be added with same pool of removed formulas - fix tracking of function symbols instead of expressions to filter replay - add nla_divisions to track (cheap) divisibility lemmas. -
