- Using `--log-file` is known to be problematic in 1.15. This presents as things being logged multiple times to the same file. The behaviour and details of this issue, as well as some preliminary attempts at fixing it are documented [here](https://github.com/kubernetes/kubernetes/issues/78734#issuecomment-501372131)

### Etcd v3.5.[0-2] data corruption

- The `WaitFor` and `WaitForWithContext` functions in the wait package have now been marked private. Callers should use the equivalent `Poll*` method with a zero duration interval. ([#115116](https://github.com/kubernetes/kubernetes/pull/115116), [@smarterclayton](https://github.com/smarterclayton))

Kubernetes will no longer ship an instance of the Cloud Controller Manager binary. Each Cloud Provider is expected to ship their own instance of this binary. Details for a Cloud Provider to create an instance of such a binary can be found [here](https://github.com/kubernetes/kubernetes/tree/master/staging/src/k8s.io/cloud-provider/sample). Anyone with questions on building a Cloud Controller Manager should reach out to SIG Cloud Provider. Questions about the Cloud Controller Manager on a...

- The "fake" clients generated by `client-gen` now have the same semantics on
  error as the real clients; in particular, a failed Get(), Create(), etc, no longer
  returns `nil`. (It now returns a pointer to a zero-valued object, like the real
  clients do.) This will break some downstream unit tests that were testing
  `result == nil` rather than `err != nil`, and in some cases may expose bugs
