- Fixed a rare race condition in kube-apiserver that could lead to missing events when a watch API request was created at the same time kube-apiserver was re-initializing its internal watch. ([#116172](https://github.com/kubernetes/kubernetes/pull/116172), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery]

- Fixed a race condition on API server startup ensuring previously created webhook configurations are effective before the first write request is admitted. ([#95783](https://github.com/kubernetes/kubernetes/pull/95783), [@roycaihw](https://github.com/roycaihw)) [SIG API Machinery]

some of the other birds tittered audibly.

  `What I was going to say,' said the Dodo in an offended tone,
`was, that the best thing to get us dry would be a Caucus-race.'

  `What IS a Caucus-race?' said Alice; not that she wanted much
to know, but the Dodo had paused as if it thought that SOMEBODY
ought to speak, and no one else seemed inclined to say anything.

* fix vmss dirty cache issue in disk attach/detach on vmss node ([#85158](https://github.com/kubernetes/kubernetes/pull/85158), [@andyzhangx](https://github.com/andyzhangx))
* fix race condition when attach/delete azure disk in same time ([#84917](https://github.com/kubernetes/kubernetes/pull/84917), [@andyzhangx](https://github.com/andyzhangx))

## Version 3.14.3

_2019-09-10_

 *  Fix: Don't lose HTTP/2 flow control bytes when incoming data races with a stream close. If this
    happened enough then eventually the connection would stall.

 *  Fix: Acknowledge and apply inbound HTTP/2 settings atomically. Previously we had a race where we
    could use new flow control capacity before acknowledging it, causing strict HTTP/2 servers to
    fail the call.

- Fixed a data race in TopologyCache when `AddHints` and `SetNodes` are called concurrently. ([#117249](https://github.com/kubernetes/kubernetes/pull/117249), [@tnqn](https://github.com/tnqn)) [SIG Apps and Network]

- Fix data race in kubelet/volumemanager ([#127919](https://github.com/kubernetes/kubernetes/pull/127919), [@carlory](https://github.com/carlory)) [SIG Apps, Node and Storage]

* Fix a race condition in the scheduler preemption logic that could cause nominatedNodeName of a pod not to be considered in one or more scheduling cycles. ([#72504](https://github.com/kubernetes/kubernetes/pull/72504), [@bsalamat](https://github.com/bsalamat))

      int rightCode = identityHashCode(right);
      if (leftCode != rightCode) {
        return leftCode < rightCode ? -1 : 1;
      }

      // identityHashCode collision (rare, but not as rare as you'd think)
      int result = getUid(left).compareTo(getUid(right));
      if (result == 0) {
        throw new AssertionError(); // extremely, extremely unlikely.
      }
      return result;
    }

* Fixed missing error checking that could cause kubelet to crash in a race condition. ([#60962](https://github.com/kubernetes/kubernetes/pull/60962), [@technicianted](https://github.com/technicianted))
* Bump Heapster to v1.5.2 ([#61396](https://github.com/kubernetes/kubernetes/pull/61396), [@kawych](https://github.com/kawych))
