Docker et des outils similaires utilisent également un **cache interne** lors de la construction de l'image : si un fichier n'a pas changé depuis la dernière construction de l'image de conteneur, alors il va **réutiliser la même couche** créée la dernière fois, au lieu de recopier le fichier et créer une nouvelle couche à partir de zéro.

- Fixed Pod stuck in `Terminating` because of `GenerateUnmapVolumeFunc` missing `globalUnmapPath` when kubelet tries to clean up all volumes that failed reconstruction. ([#123032](https://github.com/kubernetes/kubernetes/pull/123032), [@carlory](https://github.com/carlory))

- Reverted NewVolumeManagerReconstruction and SELinuxMountReadWriteOncePod feature gates to disabled by default to resolve a regression of volume reconstruction on kubelet/node restart ([#117751](https://github.com/kubernetes/kubernetes/pull/117751), [@liggitt](https://github.com/liggitt)) [SIG Storage]

- Added publishing events when enabling/disabling `TopologyAwareHints`. ([#113544](https://github.com/kubernetes/kubernetes/pull/113544), [@LiorLieberman](https://github.com/LiorLieberman))
