- `kubectl exec` and `kubectl attach` now honor the `--quiet` flag which suppresses output from the local binary that could be confused by a script with the remote command output (all non-failure output is hidden). In addition, print inline with exec and attach the list of alternate containers when we default to the first spec.container. ([#99004](https://github.com/kubernetes/kubernetes/pull/99004),...

* add spelling checking script ([#59463](https://github.com/kubernetes/kubernetes/pull/59463), [@dixudx](https://github.com/dixudx))

* Portability across systems has been increased by the use of `/usr/bin/env` in all script shebangs. ([#62657](https://github.com/kubernetes/kubernetes/pull/62657), [@matthyx](https://github.com/matthyx))

must be imported by specific e2e test suites. Init packages are provided which can be imported to re-enable the functionality that traditionally was in the core framework. If you have code that no longer compiles because of this PR, you can use the script [from a commit message](https://github.com/kubernetes/kubernetes/pull/112043/commits/dfdf88d4faafa6fd39988832ea0ef6d668f490e9) to update that code.

- Projects which use k8s.io/code-generator and invoke `generate-groups` or `generate-internal-groups.sh` have a new, simpler script (`kube_codegen.sh`) they can use.  The old scripts are deprecated but remain intact. ([#117262](https://github.com/kubernetes/kubernetes/pull/117262), [@thockin](https://github.com/thockin)) [SIG API Machinery and Instrumentation]

- Fix etcd version migration script in etcd image. ([#91925](https://github.com/kubernetes/kubernetes/pull/91925), [@wenjiaswe](https://github.com/wenjiaswe)) [SIG API Machinery]

* Users may now execute `get-kube-binaries.sh` to request a client for an OS/Arch unlike the one of the host on which the script is invoked. ([#74889](https://github.com/kubernetes/kubernetes/pull/74889), [@akutz](https://github.com/akutz))

- The scheduler prints info logs when the extender returned an error. (`--v>5`) ([#107974](https://github.com/kubernetes/kubernetes/pull/107974), [@sanposhiho](https://github.com/sanposhiho))
- The script `cluster/gce/gci/configure.sh` now supports downloading `crictl` on ARM64 nodes ([#108034](https://github.com/kubernetes/kubernetes/pull/108034), [@tstapler](https://github.com/tstapler))
