* fixes a memory leak in the kube-controller-manager observed when large numbers of pods with tolerations are created/deleted ([#65339](https://github.com/kubernetes/kubernetes/pull/65339), [@liggitt](https://github.com/liggitt))

allowed to leak this length, but will not leak // any information about the values contained in those limbs. type Nat struct { // limbs is little-endian in base 2^W with W = bits.UintSize. limbs []uint } // preallocTarget is the size in bits of the numbers used to implement the most // common and most performant RSA key size. It's also enough to cover some of // the operations of key sizes up to 4096. const preallocTarget = 2048 const preallocLimbs = (preallocTarget + _W - 1) / _W // NewNat returns...

SIG Windows is also including several addition to this release:
 - Direct Server Return (DSR) mode support, allowing large numbers of services to scale up efficiently
 - Windows containers  now honor CPU limits
 - Performance improvements for collections of metrics and summary

### Increase the Kubernetes support window to one year
