 *  New: Handy constants for `Headers.EMPTY`, `RequestBody.EMPTY`, and `ResponseBody.EMPTY`.

 *  New: OkHttp now calls `StrictMode.noteSlowCall()` when initializing TLS on Android. Use
    `StrictMode` to detect if your `OkHttpClient` is being initialized on the main thread.

 *  Upgrade: [Okio 3.12.0][okio_3_12_0].

 *  Upgrade: [Kotlin 2.1.21][kotlin_2_1_21].

## Version 3.6.0

_2017-01-29_

 *  Fix: Don't crash with a "cache is closed" error when there is an error initializing the cache.
 *  Fix: Calling `disconnect()` on a connecting `HttpUrlConnection` could cause it to retry in an
    infinite loop! This regression was introduced in OkHttp 2.7.0.

* Fix cloud-controller-manager crash when using OpenStack provider and PersistentVolume initializing controller   ([#70459](https://github.com/kubernetes/kubernetes/pull/70459), [@mvladev](https://github.com/mvladev))

- Fixed a startup probe race condition that caused main containers to remain stuck in "Initializing" state when sidecar containers with startup probes had failed initially but succeeded on restart in pods with `restartPolicy=Never`.

### Bug or Regression

- Fixed a regression since 1.27.0 in scheduler framework when running score plugins. 
  The `skippedScorePlugins` number might be greater than `enabledScorePlugins`, 
  so when initializing a slice the cap(len(skippedScorePlugins) - len(enabledScorePlugins)) is negative, 
  which is not allowed. ([#121666](https://github.com/kubernetes/kubernetes/pull/121666), [@kerthcet](https://github.com/kerthcet)) [SIG Scheduling]
