how can I verify support IN AWS sign v4?

I am still using python27.

When I upgrade my boto installation, I got the following output:

$ pip install --upgrade boto3
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

As you can see it installed boto3-1.9.167 botocore-1.12.167

So boto is of the latest version at the time of writing this question: https://github.com/boto/boto3/releases/tag/1.9.167

However I have trouble locating any release note. I just want to make sure AWS Sign v4 is supported and used in this version of boto.

How can I verify?

The botocore changelog indicates that from version 1.7.51, all s3 requests use sigv4 by default. Since boto3 is based on botocore you can safely assume that sigv4 is supported by the versions you downloaded.
