* Fixes a panic in kube-controller-manager cleaning up bootstrap tokens ([#82887](https://github.com/kubernetes/kubernetes/pull/82887), [@tedyu](https://github.com/tedyu))
* Fixed a scheduler panic when using PodAffinity. ([#82841](https://github.com/kubernetes/kubernetes/pull/82841), [@Huang-Wei](https://github.com/Huang-Wei))

### [Sanic](https://sanic.readthedocs.io/en/latest/) { #sanic }

`asyncio`に基づいた、Pythonのフレームワークの中でも非常に高速なものの一つです。Flaskと非常に似た作りになっています。

/// note | 技術詳細

Pythonの`asyncio`ループの代わりに、[`uvloop`](https://github.com/MagicStack/uvloop)が利用されています。それにより、非常に高速です。

`Uvicorn`と`Starlette`に明らかなインスピレーションを与えており、それらは現在オープンなベンチマークにおいてSanicより高速です。
