 ### Fixed
-- `CorpusReader.train_batch_gen` raises StopIteration instead of returning None if no data can be generated.
+- `CorpusReader.train_batch_gen` now correctly handles edge case when no data can be generated.
 - Decoding from saved model is now possible for arbitrary Tensorflow model topologies that have the same input and output structure via named arguments that specify where input and output to the model occur.
 - RNN CTC model class now accepts `pathlib.Path` for directory argument
 - Max epochs for model training is now correct. Previously there was an off by one error where one more than the supplied max epochs would be run in the training loop.
