   • [USER] Introduce support for preservation of machines (both Running and Failed), and the backing node (if it exists). by @thiyyakat [#1059]

   🐛 Bug Fixes

   • [OPERATOR] Exclude terminating machines when managing machineset replicas to allow for faster replacement of a failed machine. by @takoverflow [#1086]

   🏃 Others

   • [OPERATOR] Fix machines termination in machine set replica management to avoid needless scale-up of machines because of stale replica count. by @r4mek [#1069]

    • [OPERATOR] Fixed a bug where machines in the InPlaceUpdating phase were incorrectly transferred to the new machine set during inplace updates. This caused the machine controller to miss updating the phase to InPlaceUpdateSuccessful, resulting in machines getting stuck or marked as InPlaceUpdateFailed. by @acumino [#1020]

    🏃 Others

    • [OPERATOR] node.gardener.cloud/critical-components-not-ready taint is added to the node after the successful in-place update to prevent scheduling any workload before critical component pods are ready. by @acumino [#1017]
