  "message": "[SDK] Adds an SDK hash to kernels and the VM.\n\nAdds a new SDK hash to kernels and the VM which is optionally checked\nto verify kernels are built for the same SDK as the VM.\nThis helps catch incompatibilities that are currently causing\nsubtle bugs and (not so subtle) crashes.\n\nThe SDK hash is encoded in kernels as a new field in components.\nThe hash is derived from the 10 byte git short hash.\n\nThis new check can be disabled via:\n  tools/gn.py ... --no-verify-sdk-hash\n\nThis CL bumps the min. (and max.) supported kernel format version,\nmaking the VM backwards incompatible from this point back.\n\nBug: https://github.com/dart-lang/sdk/issues/41802\nChange-Id: I3cbb2d481239ee64dafdaa0e4aac36c80281931b\nReviewed-on: https://dart-review.googlesource.com/c/sdk/+/150343\nCommit-Queue: Clement Skau \u003ccskau@google.com\u003e\nReviewed-by: Jens Johansen \u003cjensj@google.com\u003e\nReviewed-by: Martin Kustermann \u003ckustermann@google.com\u003e\n",
