--------- ## Motivation Python 2.x has been deprecated for many years now and it was officially end-of-lifed 2.5 years ago (https://www.python.org/doc/sunset-python-2/). We have well reached the point by which we need to drop Python 2.7 compatibility for Pulsar client and for Pulsar functions. ## Goal Support only Python 3.5+ for Pulsar client and for Pulsar functions. ## API Changes No changes at this time, though Pulsar Python client library will be now free to use Python3 specific syntaxes and libraries. ## Changes 1. Switch the CI build to run Python client lib tests with Python3 2. Switch integration tests to use Python3 3. Stop building and distributing wheel files for Python 2.7 -- Matteo Merli <mme...@apache.org>
