Plan for dropping Python 2.7 for more. This is a major release from 0.23.4 and includes a number of API changes, new features, enhancements, and perfor- mance improvements along with a large number of bug Interval and Period data in a Series or DataFrame • Support for joining on two MultiIndexes Check the API Changes and deprecations before updating. These are the changes in pandas 0.24.0. See Release Notes is enabled through the use of extension types. Note: IntegerArray is currently experimental. Its API or implementation may change without warning. We can construct a Series with the specified dtype.
