- PodSecurityPolicy objects now support a `MayRunAs` rule for `fsGroup` and `supplementalGroups` options. This allows specifying ranges of allowed GIDs for pods/containers without forcing a default GID the way `MustRunAs` does. This means that a container to which such a policy applies to won't use any fsGroup/supplementalGroup GID if not explicitly specified, yet a specified GID must still fall in...

- The calculation of pod UIDs for static pods has changed to ensure each static pod gets a unique value - this will cause all static pod containers to be recreated/restarted if an in-place kubelet upgrade from 1.20 to 1.21 is performed. Note that draining pods before upgrading...

// Converts TF unsorted segment reduction ops to XLA HLO scatter op.

// TF unsorted segment reduction op peforms the following calculation:

// Assume segment ids' shape is [SI0, SI1, ..., SIm] and data's  shape is
// [D0, D1, ..., Dn]. Note that segment ids' shape must be a prefix of data's
// shape, so we can have data's shape represented as [SI0, SI1, ..., SIm,
