In the examples shared patch versions are not used in the `python_version` Environment Marker. For example, [this issue](https://github.com/python/peps/issues/560) led me to believe that `python_version` only considers the major and minor versions. As for the `t` suffix, I’m also not entirely sure about the background there. I vaguely remember hearing at EuroPython that it's going to stay, but I could be misremembering 😬 -- This is an automated message from the Apache Git Service.
