Release Schedule
Next Deadline: Release Cycle Begins, Sept. 5th
You could also apply to be a Release Team shadow if you submit by this Friday.

Merges
- A whole ton of golang metrics for debugging and language performance are available
- LocalStorageCapacityIsolationFSQuotaMonitoring has been reverted to Alpha due to issues with ConfigMaps, as well as being the longest single feature name in Kubernetes history
- etcd metrics are based on GroupResource; this may change how some objects are logged
- The scheduler will retry to get pod status on some kinds of errors
- API machinery errors support
errors.Ismatching - IPVS proxy will not fall back to IPTables, and will sync weights less frequently
- Health check metrics will be published by components for data collection, once everything is wired up
- Leader election logic is consistent between go and Kubernetes
- Metrics
finalURLTemplategot put back after we found out that people were still using it - Scheduler dumper offers up a list of pending pods
- Show all of rollout history in kubectl
- Scheduling framework changes won’t break the autoscaler

- Let’s test and make sure that CRDs won’t recurse forever, eh?
Testing Work: HPA scaling, kubectl storage unit test, non-graceful node shutdown, APF concurrency, loop and optimize, nodelifecycle
