  "message": "Improve compatibility with ceres::Solver\n\n1. Default linear solver is Eigen::LDLT\n2. Options::max_iterations -\u003e Options::max_num_iterations\n3. Options::error_threshold -\u003e Options::cost_threshold\n4. Options::relative_step_threshold -\u003e Options::parameter_threshold\n5. Options::initial_scale_factor -\u003e Options::initial_trust_region_radius\n6. The default values of the above parameters have been changed\n   to match those in ceres::Solver::Options\n7. Status::RUNNING has been removed\n8. Update now returns a bool instead of a Status enum and\n   the status handling has been included in the main loop.\n9. Summary::gradient_norm has been changed to Summary::gradient_max_norm\n   to match the convergence test\n10. A member variable cost_ has been added which is computed by Update\n11. The test for parameter_tolerance based convergence is made\n    more robust near zero.\n12. Use of double has been replaced by Scalar.\n13. Minor clang-formatting\n\nChange-Id: I3cb0e2fd0a0204476bb8718761dc740cdf5e42ce\n",
