- We’re working to simplify the Windows node join experience with better scripts and kubeadm. Scripts and doc updates are still in the works, but some of the needed improvements are included in 1.15.  These include:

  - `node_cpu_usage_seconds_total`
  - `node_memory_working_set_bytes`
  - `pod_cpu_usage_seconds_total`
  - `pod_memory_working_set_bytes`
  - `resource_scrape_error`
