Here's a little bit of that history.

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.

### Features

- 'The `IPv6DualStack` feature gate for external cloud providers was removed.
  (The feature became GA in 1.23 and the gate was removed for all other
  components several releases ago.) If you were still manually
  enabling it you must stop now.' ([#116255](https://github.com/kubernetes/kubernetes/pull/116255), [@danwinship](https://github.com/danwinship))
