- The kubelet now creates an iptables chain named `KUBE-IPTABLES-HINT` in
  the `mangle` table. Containerized components that need to modify iptables
  rules in the host network namespace can use the existence of this chain
  to more-reliably determine whether the system is using iptables-legacy or

- Kubeadm: upgrade plan now prints a table indicating the state of known component configs prior to upgrade ([#88124](https://github.com/kubernetes/kubernetes/pull/88124), [@rosti](https://github.com/rosti)) [SIG Cluster Lifecycle]

* Bump up glbc version to 0.9.0-beta.1 ([#40565](https://github.com/kubernetes/kubernetes/pull/40565), [@bprashanth](https://github.com/bprashanth))
* Enable lazy inode table and journal initialization for ext3 and ext4 ([#38865](https://github.com/kubernetes/kubernetes/pull/38865), [@codablock](https://github.com/codablock))

The main milestones for SIG Network this release are the graduation of IPVS-based load balancing and CoreDNS to general availability.

IPVS is an alternative approach to in-cluster load balancing that uses in-kernel hash tables rather than the previous iptables approach, while CoreDNS is a replacement for kube-dns for service discovery.

*   Termination grace period for the calico/node add-on DaemonSet has been eliminated, reducing downtime...

- Implemented logging for failed transactions and the full table in `kube-proxy` with 
`nftables` when using log level 4 or higher. Logging is rate-limited to one entry every 24 hours

Consider a compiled a package containing the package clause
<code>package math</code>, which exports function <code>Sin</code>, and
installed the compiled package in the file identified by
<code>"lib/math"</code>.
This table illustrates how <code>Sin</code> is accessed in files
that import the package after the
various types of import declaration.
