  "message": "Add covariance matrix for a vector of parameters\n\nComputing the covariance matrix for a number of parameter blocks\npreviously required adding all parameter blocks to the computation and\nsubsequently assembling the matrix by concatenating all the blocks.\n\nThis patch adds the computation of the covariance matrix for a vector\nof parameter blocks. All covariance block pairs are added automatically\nand the resulting covariance matrix is assembled in the order the\nparameter blocks appear.\n\nChange-Id: I3b70c63f16862adc23a1d7fb7a21dde4e68abe9a\n",
