#### Docker runtime Known Issues

- Kernel crash with Aufs storage driver on Debian Jessie ([#27885](https://github.com/kubernetes/kubernetes/issues/27885))
  - Consider running the *new* [kubernetes node problem detector](https://github.com/kubernetes/node-problem-detector) to identify this (and other) kernel issues automatically.

- File descriptors are leaked in docker v1.11 ([#275](https://github.com/docker/containerd/issues/275))

Now, whenever a browser is creating a user with a password, the API will return the same password in the response.

In this case, it might not be a problem, because it's the same user sending the password.

But if we use the same model for another *path operation*, we could be sending our user's passwords to every client.

## Version 5.0.0-alpha.2

_2021-01-30_

**In this release MockWebServer has a new Maven coordinate and package name.** A longstanding
problem with MockWebServer has been its API dependency on JUnit 4. We've reorganized things to
remove that dependency while preserving backwards compatibility.
