- We released autoscaling/v2beta2, which cleans up and unifies the API
- We improved readiness detection and smoothing to work well in a larger variety or use cases

### SIG-Azure

Sig Azure was focused on two primary new alpha features:
- Adding Azure Availability Zones support to cloud provider.
- Supporting Cross RG resources (disks, Azure File and node [Experimental]

- `kubectl run --env` no longer supports CSV parsing. To provide multiple environment
  variables, use the `--env` flag multiple times instead. Example: `--env ONE=1 --env TWO=2` instead of `--env ONE=1,TWO=2`.

- Removed deprecated command `kubectl stop`.

- Kubectl can now use http caching for the OpenAPI schema. The cache
