- Specific error message on failed rolling update issued by older kubectl against 1.4 master ([#32751](https://github.com/kubernetes/kubernetes/issues/32751))
- bump master cidr range from /30 to /29 ([#32886](https://github.com/kubernetes/kubernetes/issues/32886))
- non-hostNetwork daemonsets will almost always have a pod that fails to schedule ([#32900](https://github.com/kubernetes/kubernetes/issues/32900))

#### GlusterFS
* The glusterfs dynamic volume provisioner will now choose a unique GID for new persistent volumes from a range that can be configured in the storage class with the "gidMin" and "gidMax" parameters. The default range is 2000 - 2147483647 (max int32). ([#37886](https://github.com/kubernetes/kubernetes/pull/37886), [@obnoxxx](https://github.com/obnoxxx))

* When using IP aliases, use a secondary range rather than subnetwork to reserve cluster IPs. ([#51690](https://github.com/kubernetes/kubernetes/pull/51690), [@bowei](https://github.com/bowei))

- Expand scheduler priority functions and scheduling framework plugins' node score range to [0, 100]. Note: this change is internal and does not affect extender and RequestedToCapacityRatio custom priority, which are still expected to provide a [0, 10] range.
