+* Fixes a bug that was causing gradients from one of the worker nodes to be added twice resulting in incorrect `all_reduce` results under some conditions.
+
+*Known Issues:*
+
+* SageMaker distributed data parallel still is not efficient when run using a single node. For the best performance, use multi-node distributed training with `smdistributed.dataparallel`. Use a single node only for experimental runs while preparing your training pipeline.
