We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Package not classified as Python 3 compatible 
* `sentry-sdk` is classified as not Python 3 compatible by [pyup](https://pyup.io) when it actually is - e.g. [https://pyup.io/repos/github/pushresume/backend](https://pyup.io/repos/github/pushresume/backend)

* `setup.py` classifiers should be updated with `Programming Language :: Python :: 3`
