This release modifies the behavior of setup.py with respect to dependencies. Previously, boto3 and other AWS-related packages were installed by default. Now, in order to install them, you need to run either:

to install the AWS dependencies only, or

pip install smart_open[all]

to install all dependencies, including AWS, GCS, etc.
