// TODO(josh11b): Public API functions for exporting the above.

// GraphDef compatibility versions (the versions field in graph.proto).
//
// Each graph has producer and min_consumer versions, and each
// consumer has its own version and a min_producer.  In addition, graphs can
// mark specific consumer versions as bad (to prevent bugs from executing).
// A consumer will execute a graph if the consumer's version is at least the
// graph's min_consumer, the graph's producer version is at least the consumer's
// min_producer, and the consumer version isn't specifically disallowed by the
// graph.
//
// By default, newly created graphs have producer version TF_GRAPH_DEF_VERSION
// min_consumer TF_GRAPH_DEF_MIN_CONSUMER, and no other bad consumer versions.
//
// Version history:
//
// 0. Graphs created before GraphDef versioning
// 1. First real version (2dec2015)
// 2. adjust_contrast only takes float, doesn't perform clamping (11dec2015)
// 3. Remove TileGrad, since it was equivalent to reduce_sum (30dec2015)
// 4. When support for this version is removed, we can safely make AttrValue
//    parsing more strict with respect to empty list values (see
//    111635679, 7jan2016).
// 5. Graphs are wholly-validated during Session::Create() (7jan2016).
// 6. TensorFlow is scalar strict within Google (27jan2016).
// 7. Remove TopK in favor of TopKV2 (5feb2016).
// 8. Replace RandomCrop from C++ with pure Python (5feb2016).
// 9. Deprecate batch_norm_with_global_normalization (16feb2016).
// 10. Deprecate conv3d_backprop_{filter,input} (10jun2016).
