  "message": "Refactor Covariance::Options::algorithm_type.\n\nTHIS IS AN API BREAKING CHANGE.\n\nDecouple the algorithm from the sparse linear algebra\nlibrary being used to perform the computation.\n\nBefore this change\n\nCovariance::AlgorithmType had values\n\nDENSE_SVD\nEIGEN_SPARSE_QR\nSUITE_SPARSE_QR\n\nThis has been replaced by two enums now.\n\nCovariance::Options::sparse_linear_algebra_library_type\nwhich can take values EIGEN_SPARSE, SUITE_SPARSE or CX_SPARSE.\nThe last one is currently not supported.\n\nAnd Covariance::Options::algorithm_type takes values\n\nDENSE_SVD\nSPARSE_QR\n\nThis sets the stage for future extensions of the covariance\ncomputation algorithm.\n\nAlso as part of this change, the covariance computation chapter\nhas been made a top level chapter on its own instead of being\nburied deep inside the Solving Non-linear Least Squares problem.\n\nChange-Id: Ibfbf60902d8d17694d9ff585047a5a57d329ab22\n",
