  * “kubectl edit <list>” will open the editor multiple times, once for each
resource in the list.
  * If you create HPA object using autoscaling/v1 API without specifying
targetCPUUtilizationPercentage and read it using kubectl it will print default
value as specified in extensions/v1beta1 (see details in [#23196](https://github.com/kubernetes/kubernetes/issues/23196)).

* Changes secret, configMap, downwardAPI and projected volumes to mount read-only, instead of allowing applications to write data and then reverting it automatically. Until version 1.11, setting the feature gate ReadOnlyAPIDataVolumes=false will preserve the old behavior. ([#58720](https://github.com/kubernetes/kubernetes/pull/58720),...

### Файлы и async { #files-and-async }

В большинстве случаев «файлоподобные» объекты по умолчанию не совместимы с async и await.

Например, у них нет `await file.read()` или `async for chunk in file`.

И во многих случаях чтение таких объектов будет блокирующей операцией (которая может заблокировать цикл событий), потому что данные читаются с диска или из сети.
