  +### Update the operator version map
  +
  +The last step is to add the new version info into the operator version map. This
  +step is required because we need generate the model's minimum required runtime
  +version based on this version map.
  +
  +To do this, you need to add a new map entry in `lite/toco/tflite/op_version.cc`.
  +
  +In this example, it means you need to add the following into `op_version_map`:
  +```
  +{{OperatorType::kConv, 3}, "kPendingReleaseOpVersion"}

  +(`kPendingReleaseOpVersion` will be replaced with the appropriate release
  +version in the next stable release.)

  ### Delegation Implementation
  TensorFlow Lite provides a delegation API which enables delegating ops to
