The following versions of Docker Engine are supported - *[v1.10](https://github.com/kubernetes/kubernetes/issues/19720)*, *[v1.11](https://github.com/kubernetes/kubernetes/issues/23397)*
Although *v1.9* is still compatible, we recommend upgrading to one of the supported versions.
All prior versions of docker will not be supported.

#### ThirdPartyResource

- Fixed #73264 `cpuPeriod` was not reset, but used as set via flag, although it was disabled via alpha gate ([#73342](https://github.com/kubernetes/kubernetes/pull/73342), [@szuecs](https://github.com/szuecs))

- Kubernetes 1.24 is built with go1.18, which will no longer validate certificates...

plain backslash <code>\</code> followed by exactly three octal digits.
In each case the value of the literal is the value represented by
the digits in the corresponding base.
</p>

<p>
Although these representations all result in an integer, they have
different valid ranges.  Octal escapes must represent a value between
0 and 255 inclusive.  Hexadecimal escapes satisfy this condition

- `kubectl prune v2`: Switched annotation from `contains-group-resources` to `contains-group-kinds`,
  because this is what we defined in the KEP and is clearer to end-users. Although the functionality is
  in `alpha`, we will recognize the prior annotation. This migration support will be removed in `beta`/`GA`. ([#118942](https://github.com/kubernetes/kubernetes/pull/118942), [@justinsb](https://github.com/justinsb))

## Changelog since v1.12.0

### Other notable changes

* kubeadm now allows mixing of init/cluster and join configuration in a single YAML file (although a warning gets printed in this case).  ([#69426](https://github.com/kubernetes/kubernetes/pull/69426), [@rosti](https://github.com/rosti))

        convolution algorithms, a regression that was introduced in v2.5. Note
        that nondeterministic out-of-memory events while selecting algorithms
        could still lead to nondeterminism, although this is very unlikely. This
        additional, unlikely source will be eliminated in a later version.
    *   Add deterministic GPU implementations of:
        *   `tf.function(jit_compile=True)`'s that use `Scatter`.

Since 1.21, Kubernetes clusters are enabled to support dual-stack networking by default.
In 1.23, the `IPv6DualStack` feature gate is removed.
The use of dual-stack networking is not mandatory.
Although clusters are enabled to support dual-stack networking, Pods and Services continue to default to single-stack.

### Pydantic v1

**This version of FastAPI still supports Pydantic v1**. And although Pydantic v1 will be deprecated at some point, it will still be supported for a while.
