 - Fault Tolerant Manual
     * Add `_SupportsStateDict` protocol to detect if classes are stateful ([#10646](https://github.com/PyTorchLightning/pytorch-lightning/issues/10646))
     * Add `_FaultTolerantMode` enum used to track different supported fault tolerant modes ([#10645](https://github.com/PyTorchLightning/pytorch-lightning/issues/10645))
+    * Add a `_rotate_worker_indices` utility to reload the state according the latest worker ([#10647](https://github.com/PyTorchLightning/pytorch-lightning/issues/10647))
