[SIG Network][] is responsible for networking components, APIs, and plugins in Kubernetes.

For the 1.8 release, SIG Network enhanced the NetworkPolicy API to support pod egress traffic policies.
The SIG also provided match criteria that allow policy rules to match a source or destination CIDR. Both features are in beta. SIG Network also improved the kube-proxy to include an alpha IPVS mode in addition to the current iptables and userspace modes.

- Added matchConditions field to ValidatingAdmissionPolicy and enabled support for CEL based custom match criteria. ([#116350](https://github.com/kubernetes/kubernetes/pull/116350), [@maxsmythe](https://github.com/maxsmythe))
- Added new option to the `InterPodAffinity` scheduler plugin to ignore existing

* When using `kubectl delete` with selection criteria, the defaults to is now to ignore "not found" errors. Note that this does not apply when deleting a speciic resource. ([#63490](https://github.com/kubernetes/kubernetes/pull/63490), [@deads2k](https://github.com/deads2k))

- Fix a bug that Pods could stuck in the unschedulable pod pool 
  if they're rejected by PreEnqueue plugins that could change its result by a change in resources apart from Pods.
  
  DRA plugin is the only plugin that meets the criteria of the bug in in-tree, 
  and hence if you have `DynamicResourceAllocation` feature flag enabled, 

- A working knowledge of AWS S3 API behaviors and corner cases.

## Pre-requisite for backporting any fixes

Fixes that are allowed a backport must satisfy any of the following criteria's:

- A fix must not be a feature, for example.

precisa criar os recursos para uma tarefa de background dentro dela mesma, e usar internamente apenas dados que não dependam de recursos de dependências com `yield`.

Por exemplo, em vez de utilizar a mesma sessão do banco de dados, você criaria uma nova sessão dentro da tarefa de background, e você obteria os objetos do banco de dados utilizando essa nova sessão. E então, em vez de passar o objeto obtido do banco de dados como um parâmetro para a função da tarefa de background, você passaria...
