* Fixed racy panics when using fake watches with ObjectTracker ([#61195](https://github.com/kubernetes/kubernetes/pull/61195), [@grantr](https://github.com/grantr))
* Fixed mounting of UNIX sockets(and other special files) in subpaths ([#61480](https://github.com/kubernetes/kubernetes/pull/61480), [@gnufscied](https://github.com/gnufied))

* PodSpecs containing parent directory references such as `..` (for example, `../bar`) in hostPath volume path or in volumeMount subpaths must be changed to the simple absolute path. Backsteps `..` are no longer allowed.([#47290](https://github.com/kubernetes/kubernetes/pull/47290), [@jhorwit2](https://github.com/jhorwit2)).

  If the `subPath` is a file rather than a directory, Pods may fail to start ([#45613](https://github.com/kubernetes/kubernetes/issues/45613)).

  **Do not upgrade to v1.6.3** if your cluster may run Pods with such subPaths.
