### Windows

This release continues to enable more existing features on Windows, including container CPU resources, image filesystem stats, and flexvolumes. It also adds Windows service control manager support and experimental support for Hyper-V isolation of single-container pods.

🚨 This is probably the last release (or one of the last releases) to support Python 3.6. 🔥

Python 3.6 reached the [end-of-life and is no longer supported by Python](https://www.python.org/downloads/release/python-3615/) since around a year ago.

You hopefully updated to a supported version of Python a while ago. If you haven't, you really should.
