* Keep commits discrete. Avoid including multiple unrelated changes in a single commit.
* Keep commits self-contained. Avoid spreading a single change across multiple commits. A single commit should make sense in isolation.

### Testing changes

After making changes, you can test your code in 2 ways:

#### Run tests

s/concepts/configuration/assign-pod-node/). Node affinity/anti-affinity allow you to specify rules for restricting which node(s) a pod can schedule onto, based on the labels on the node. Pod affinity/anti-affinity allow you to specify rules for spreading and packing pods relative to one another, across arbitrary topologies (node, zone, etc.) These affinity rules are now be specified in a new-in-1.6 `affinity` field of the PodSpec. Kubernetes 1.6 continues to support the alpha `scheduler.alpha.ku...

- The calculations for Pod topology spread skew now exclude nodes that
  don't match the node affinity/selector. This may lead to unschedulable pods if you previously had pods
  matching the spreading selector on those excluded nodes (not matching the node affinity/selector),
  especially when the `topologyKey` is not node-level. Revisit the node affinity and/or pod selector in the

large collections. Streaming list responses can be disabled via the `StreamingJSONListEncoding` feature gate. ([#129334](https://github.com/kubernetes/kubernetes/pull/129334), [@serathius](https://github.com/serathius)) [SIG API Machinery, Architecture and Release]

  So they began solemnly dancing round and round Alice, every now
and then treading on her toes when they passed too close, and
waving their forepaws to mark the time, while the Mock Turtle
sang this, very slowly and sadly:--


`"Will you walk a little faster?" said a whiting to a snail.
"There's a porpoise close behind us, and he's treading on my
 tail.
See how eagerly the lobsters and the turtles all advance!

- Introduces new alpha functionality to the reflector, allowing user to enable API streaming.
  
  To activate this feature, users can set the `ENABLE_CLIENT_GO_WATCH_LIST_ALPHA` environmental variable.
  It is important to note that the server must support streaming for this feature to function properly.
  If streaming is not supported by the server, the reflector will revert to the previous method

- Fix system default topology spreading when nodes don't have zone labels. Pods correctly spread by default now. ([#105046](https://github.com/kubernetes/kubernetes/pull/105046), [@alculquicondor](https://github.com/alculquicondor))

### (No, really, you MUST read this before you upgrade)

- The StreamingProxyRedirects feature and `--redirect-container-streaming` flag are deprecated, and will be removed in a future release. The default behavior (proxy streaming requests through the kubelet) will be the only supported option.
