- `kubelet` allows pods to use the `net.ipv4.tcp_fin_timeout`, “net.ipv4.tcp_keepalive_intvl”
  and “net.ipv4.tcp_keepalive_probes“ sysctl by default; Pod Security Admission
  allows this sysctl in `v1.29+` versions of the baseline and restricted policies. ([#121240](https://github.com/kubernetes/kubernetes/pull/121240), [@HirazawaUi](https://github.com/HirazawaUi))
- `kubelet` now allows pods to use the `net.ipv4.tcp_keepalive_time` sysctl by default

                  to other services in the mesh.

/// tip | "Dica"

O IP `0.0.0.0` é comumente usado para significar que o programa escuta em todos os IPs disponíveis naquela máquina/servidor.

///

A interface de documentação também precisaria do OpenAPI schema para declarar que API `server` está localizado em `/api/v1` (atrás do proxy). Por exemplo:

```JSON hl_lines="4-8"

- Allow pods to use the `net.ipv4.tcp_rmem` and `net.ipv4.tcp_wmem` sysctl by default
  when the kernel version is 4.15 or higher. With the kernel 4.15 the sysctl became namespaced.

```

/// tip

The IP `0.0.0.0` is commonly used to mean that the program listens on all the IPs available in that machine/server.

The docs UI would also need the OpenAPI schema to declare that this API `server` is located at `/api/v1` (behind the proxy). For example:

```JSON hl_lines="4-8"

- Added support to the kube-proxy nodePortAddresses / --nodeport-addresses option to
  accept the value "primary", meaning to only listen for NodePort connections
  on the node's primary IPv4 and/or IPv6 address (according to the Node object).
  This is strongly recommended, if you were not previously using
  --nodeport-addresses, to avoid surprising behavior.

- Fixed a regression in kube-proxy where it might refuse to start if given
  single-stack IPv6 configuration options on a node that has both IPv4 and
  IPv6 IPs. ([#121008](https://github.com/kubernetes/kubernetes/pull/121008), [@danwinship](https://github.com/danwinship)) [SIG Network]

- Fix endpoints status out-of-sync when the pod state changes rapidly ([#125675](https://github.com/kubernetes/kubernetes/pull/125675), [@tnqn](https://github.com/tnqn)) [SIG Apps, Network and Testing]
- For statically provisioned PVs, if its volume source is CSI type or it has migrated annotation, when it's deleted, the PersisentVolume controller won't changes its phase to the Failed state.
