  "message": "Enable mixed precision solves.\n\n1. Add Solver::Options::use_mixed_precision_solves,\n   and Solver::Options::max_num_refinement_iterations.\n2. Make SparseCholesky::Create return a unique_ptr.\n3. SparseCholesky::Create now takes LinearSolver::Options\n   as an argument.\n4. IterativeRefiner\u0027s constructor does not require num_cols\n   as an argument.\n5. SparseNormalCholeskySolver now uses a separate rhs vector.\n\nThis basic implementation results in a 10% reduction in solver time\nand 30% reduction in linear solver memory usage.\n\nChange-Id: I6830f32cae2febf082d2733262eb2c9f0482b0ea\n",
