- New APIs to allow adding/removing pods from pre-calculated prefilter state in the scheduling framework ([#82912](https://github.com/kubernetes/kubernetes/pull/82912), [@ahg-g](https://github.com/ahg-g))
- Added Clone method to the scheduling framework's PluginContext and ContextData. ([#82951](https://github.com/kubernetes/kubernetes/pull/82951), [@ahg-g](https://github.com/ahg-g))

### Bug or Regression

- ## Changelog
  
  ### General
  - Fix priority expander falling back to a random choice even though there is a higher priority option to choose
  - Clone `kubernetes/kubernetes` in `update-vendor.sh` shallowly, instead of fetching all revisions
  - Speed up binpacking by reducing the number of PreFilter calls (call once per pod instead of #pods*#nodes times)

Volume cloning enables users to specify another PVC as a "DataSource" when provisioning a new volume. If the underlying storage system supports this functionality and implements the "CLONE_VOLUME" capability in its CSI driver, then the new volume becomes a clone of the source volume.

These changes are reflected in the following Kubernetes enhancements:
([#625](https://github.com/kubernetes/enhancements/issues/625))

- Fixed kubectl bug where bash completions don't work if `--context` flag is specified with a value that contains a colon. ([#107439](https://github.com/kubernetes/kubernetes/pull/107439), [@brianpursley](https://github.com/brianpursley))
