This is a major release from 0.20.3 and includes a number of API changes, deprecations, new features, enhancements, and performance improvements along with a large number of bug fixes. We recommend that all users upgrade to this version. Highlights include: - Integration with Apache Parquet , including a new top-level read_parquet function and a DataFrame.to_parquet method, see here . - New user-facing dtype pandas.api.types.CategoricalDtype for specifying categoricals independent of the data, see here . - The behavior of sum and prod on all-NaN Series/DataFrames is now consistent and no longer depends on whether bottleneck is installed, see here . - Compatibility fixes for pypy, see here . - Additions to the drop, reindex, and rename API to make them more consistent, see here - Addition of the new methods DataFrame.infer_objects (see here ) and GroupBy.pipe (see here ). - Indexing with a list of labels, where one or more of the labels is missing, is deprecated and will raise a KeyError in a future version, see here . Check the whatsnew for detailed changes, including backwards incompatible changes and deprecations . Please report any issues you find on the pandas issue tracker . Binary packages will be available in the defaults and conda-forge channels shortly. conda install pandas Wheels and a source distribution are available on PyPI. pip install --upgrade pip setuptools pip install --upgrade --upgrade-strategy=only-if-needed pandas Tom
