TPU Subslicing (also known as Dynamic Subslicing) is now generally available for

## Feature Feature TPU Subslicing (also known as Dynamic Subslicing) is now generally available for Ironwood (TPU7x). This feature enables you to incrementally provision node pools for a cube or litepod, breaking them into smaller slices (subslices) to run workloads requiring smaller topologies. Updates in this GA release include: * **Dynamic sub-slicing** (topologies smaller than `4x4x4`, such as `2x2x1`,`2x2x2`, `2x2x4`, and `2x4x4`): Supported in GKE version`1.36.0-gke.3712000` or later. * **Dynamic super-slicing** (topologies `4x4x4` or larger): Supported in GKE version `1.35.2-gke.1842000` or later. * **Partition Health Labels**: The partition state label is updated to`cloud.google.com/gke-tpu-partition-[shape]-state` to specify smaller subslice shapes. It also introduces `UNSET` and `INCOMPLETE` states. Support for the `DEGRADED` state only applies to the top-level `4x4x4` topology, and not for smaller sub-slicing topologies.
