- Promote NodeLease feature to GA.
The feature make Lease object changes an additional healthiness signal from Node. Together with that, we reduce frequency of NodeStatus updates to 5m by default in case of no changes to status itself ([#84351](https://github.com/kubernetes/kubernetes/pull/84351), [@wojtek-t](https://github.com/wojtek-t))

- `--log-flush-frequency` had no effect in several commands or was missing. Help and warning texts were not always using the right format for a command (`add_dir_header` instead of `add-dir-header`). Fixing this included cleaning up flag handling in component-base/logs: that package no longer adds flags to the global flag sets. Commands which want the klog and `--log-flush-frequency` flags must explicitly call `logs.AddFlags`; the new `cli.Run` does...

- Added validation to ensure `log-flush-frequency` is a positive value, returning an error instead of causing a panic. ([#133540](https://github.com/kubernetes/kubernetes/pull/133540), [@BenTheElder](https://github.com/BenTheElder)) [SIG Architecture, Instrumentation, Network and Node]

 - Reduced frequency of DescribeVolumes calls of AWS API when attaching/detaching a volume.

* We change the default attach_detach_controller sync period to 1 minute to reduce the query frequency through cloud provider to check whether volumes are attached or not. ([#41363](https://github.com/kubernetes/kubernetes/pull/41363), [@jingxu97](https://github.com/jingxu97))

## Changes to Major Components
### API Server

of this functionality is to improve efficiency: manually freeing memory
before a garbage collection delays that cycle. Less frequent cycles means
the CPU cost of the garbage collector is incurred less frequently.

This functionality in this package is mostly captured in the Arena type.
Arenas allocate large chunks of memory for Go values, so they're likely to

- Scrape frequency of metrics-server has been increased to 30s.([#68127](https://github.com/kubernetes/kubernetes/pull/68127), [@serathius](https://github.com/serathius))
