### Instrumentation

to ppc64le. // Some changes were needed due to differences in // the Go opcodes and/or available instructions // between s390x and ppc64le. // 1. There were operand order differences in the // VSUBUQM, VSUBCUQ, and VSEL instructions. // 2. ppc64 does not have a multiply high and low // like s390x, so those were implemented using // macros to compute the equivalent values. // 3. The LVX, STVX instructions on ppc64 require // 16 byte alignment of the data. To avoid that // requirement, data is loaded...

- The `client.authentication.k8s.io/v1alpha1` ExecCredential has been removed. If you are using a client-go credential plugin that relies on the v1alpha1 API please contact the distributor of your plugin for instructions on how to migrate to the v1 API.

### Documentation

- Updated the instructions for deploying the sample app. ([#82785](https://github.com/kubernetes/kubernetes/pull/82785), [@ashish-billore](https://github.com/ashish-billore)) [SIG API Machinery]

### Failing Test

- Kubeadm: fix a bug when using external CA mode and trying to upgrade to 1.29 using "kubeadm upgrade apply". Show a warning that kubeadm cannot sign the new "super-admin.conf" as the host does not have a CA and show some instructions on how to manually migrate to the separate "admin.conf" and "super-admin.conf" kubeconfig files.

- kubeadm: fixed a misleading output (typo) about control-plane joining instructions when executing the "kubeadm init" command. ([#128118](https://github.com/kubernetes/kubernetes/pull/128118), [@amaddio](https://github.com/amaddio))

from the value obtained by executing and rounding the instructions individually.
An explicit <a href="#Numeric_types">floating-point type</a> <a href="#Conversions">conversion</a> rounds to
the precision of the target type, preventing fusion that would discard that rounding.
