  "message": "Enable support for AVX instructions for Jets.\n\n- Eigen versions \u003c 3.3 only supported SIMD instructions that required\n  16-byte alignment (SSE), whereas Eigen \u003e\u003d 3.3 also supports AVX\n  instructions which require 32+-byte alignment.\n- Previously we only ever requested 16-byte alignment for Jets (if \u003e\u003d\n  C++11 was enabled) which resulted in Eigen assertions being triggered\n  on some compilers as reported as Issue #251:\n  https://github.com/ceres-solver/ceres-solver/issues/251.\n- Now we use Eigen’s EIGEN_MAX_ALIGN_BYTES macro, defined in Eigen \u003e\u003d\n  3.3 to specify the byte alignment for Jets when C++11 is enabled for\n  Eigen \u003e\u003d 3.3.  For Eigen versions \u003c 3.3, we maintain the previous\n  behaviour of 16.\n\nChange-Id: I749af7a70ae794e0c2a59301128db781e338422c\n",
