## Bug Fixes and Other Changes

*   Numerous C++ API updates.
*   New op: `parallel_stack`.
*   Introducing common tf io compression options constants for
    RecordReader/RecordWriter.
*   Add `sparse_column_with_vocabulary_file`, to specify a feature column that
    transform string features to IDs, where the mapping is defined by a
    vocabulary file.
