- Graduated `PodObservedGenerationTracking` feature to beta and had it on by default. This feature meant that the top level `status.observedGeneration` and `status.conditions[].observedGeneration` fields in Pods were populated to reflect the `metadata.generation` of the podspec at the time that the status or condition was reported.

**Affected Versions**:
  - kube-apiserver v1.29.0 - v1.29.3
  - kube-apiserver v1.28.0 - v1.28.8
  - kube-apiserver <= v1.27.12

**Fixed Versions**:
  - kube-apiserver v1.29.4

* client-go: restores behavior of populating the BearerToken field in rest.Config objects constructed from kubeconfig files containing tokenFile config, or from in-cluster configuration. An additional BearerTokenFile field is now populated to enable constructed clients to periodically refresh tokens.

- Feature gates CSIMigration to Beta (on by default) and CSIMigrationGCE to Beta (off by default since it requires installation of the GCE PD CSI Driver) ([#85231](https://github.com/kubernetes/kubernetes/pull/85231),...

Conversely, when comparing types, a known type argument
(a type argument for which a map entry already exists)
takes the place of its corresponding type parameter.
As type inference progresses, the map is populated more and more
until all equations have been considered, or until unification fails.
Type inference succeeds if no unification step fails and the map has
an entry for each type parameter.

`container.seccomp.security.alpha.kubernetes.io`, deprecated since v1.19, was partially removed. Kubelets no longer support the annotations, use of the annotations in static pods is no longer supported, and the seccomp annotations are no longer auto-populated when pods with seccomp fields are created. Auto-population of the seccomp fields from the annotations is planned to be removed in 1.27. Pods  should use the corresponding pod or container `securityContext.seccompProfile` field instead.

- Kubeadm: added the "--cleanup-tmp-dir" flag for `kubeadm reset`. It will cleanup the contents of `/etc/kubernetes/tmp`. The flag is...

- The `transformer_failures_total` metric is deprecated in favor of `transformation_operation_total`. The old metric will continue to be populated but will be removed in a future release. ([#70715](https://github.com/kubernetes/kubernetes/pull/70715), [@immutableT](https://github.com/immutableT))

  Notes:
   * Tika supports a wider range of match types than Freedesktop does
   * Glob patterns must be unique, if there's a clash assign to the most
     popular format
   * The main mime type should be the canonical one, use aliases for any
     other widely used forms
   * Where there's a hierarchy in the types, list it via a parent
   * Highly specific magic matches get a high priority
