**Minor Improvements**

- The argument ``s3folder_config`` in ``config_pattern.api.multi_env_json.Config.deploy`` and ``config_pattern.api.multi_env_json.Config.delete`` method now can be a mapper of ``s3folder_config``, so that you can use different S3 bucket folder for different environments.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
**Minor Improvements**

- The argument ``bsm`` in ``config_pattern.api.multi_env_json.Config.deploy`` and ``config_pattern.api.multi_env_json.Config.delete`` method now can be a mapper of ``bsm``, so that you can use different AWS boto session for different environments.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
**Breaking Changes**

- ``1.X.Y`` is not compatible with ``0.X.Y`` at all.
- The config json file schema is completely redesigned to embrace "inheritance hierarchy" and advanced "config merge" features.

**Features and Improvements**

- Allow JSON path notation to apply shared config values.
- Allow merging dict, list of dict, deeply nested dict or list of dict.
- Add a :mod:`~config_patterns.patterns.hierarchy` that implements "inheritance hierarchy" pattern, and can be used independently.
- Add a :mod:`~config_patterns.patterns.merge_key_value.py` that implements "config merge" pattern, and can be used independently.

**Miscellaneous**

- Update the example Jupyter Notebook.
