  "message": "Fix a bug in TrustRegionMinimizer.\n\nLocalParameterization::Plus is allowed to return false when for some\nreason the operation cannot be performed. Uptil now, this would\ncause the TrustRegionMinimizer to terminate with a numerical failure.\n\nThis is not correct behaviour. Just like CostFunction::Evaluate,\nreturning false from LocalParameterization::Plus should result\nin the current step to be rejected rather than the entire optimization\ncoming to a halt.\n\nLineSearchMinimizer has also been updated to use the same pattern.\n\nThanks to Michael Vitus for reporting this.\n\nChange-Id: I1351966bc6db3bf6cd46387b78d4e52a9df51696\n",
