+## Breaking changes
+
+* Required Python 3.8 or newer.
+
+This requirement stems from underlying package requirements, most notably that of the NumPy package (`numpy>=1.24`).
+
+Portions of the SkLearn2PMML package may be usable with earlier Python versions.
+For example, the `sklearn2pmml.sklearn2pmml(estimator, pmml_path)` utlity function should work with any Python 2.7, 3.4 or newer version.
+
+* Migrated setup from `distutils` to `setuptools`.
+
+* Migrated unit tests from `nose` to `pytest`.
+
+Testing the (source checkout of-) package:
+
+```
+python -m pytest .
+```
+
+## New features
+
+* Added command-line interface to the `sklern2pmml.sklearn2pmml()` utility function.
+
+Sample usage:
+
+```
+python -m sklearn2pmml --input pipeline.pkl --output pipeline.pmml
+```
+
+Getting help:
+
+```
+python -m sklearn2pmml --help
+```
+
+* Added `sklearn2pmml` command-line application.
+
+Sample usage:
+
+```
+sklearn2pmml -i pipeline.pkl -o pipeline.pmml
+```
+
+## Minor improvements and fixes

 # Usage #
 
+## Command-line application ##
+
+The `sklearn2pmml` module is executable.
+The main application loads the estimator object from the Pickle file (`-i` or `--input`; supports `joblib`, `pickle` or `dill` variants), performs the conversion, and saves the result to a PMML file (`-o` or `--output`):
+
+```
+python -m sklearn2pmml --input pipeline.pkl --output pipeline.pmml
+```
+
+Getting help:
+
+```
+python -m sklearn2pmml --help
+```
+
+On some platforms, the [Pip](https://pypi.org/project/pip/) package installer additionally makes the main application available as a top-level command:
+
+```
+sklearn2pmml --input pipeline.pkl --output pipeline.pmml

   * If the `PMMLPipeline.fit(X, y)` method is invoked with `pandas.DataFrame` or `pandas.Series` object as an `X` argument, then its column names are used as feature names. Otherwise, feature names default to "x1", "x2", .., "x{number_of_features}".
   * If the `PMMLPipeline.fit(X, y)` method is invoked with `pandas.Series` object as an `y` argument, then its name is used as the target name (for supervised models). Otherwise, the target name defaults to "y".
 2. Fit and validate the pipeline as usual.
 3. Optionally, compute and embed verification data into the `PMMLPipeline` object by invoking `PMMLPipeline.verify(X)` method with a small but representative subset of training data.
-4. Convert the `PMMLPipeline` object to a PMML file in local filesystem by invoking utility method `sklearn2pmml.sklearn2pmml(pipeline, pmml_destination_path)`.
