present in earlier versions of OkHttp.
 *  New: Accept user-provided trust managers in `OkHttpClient.Builder`. This
    allows OkHttp to satisfy its TLS requirements directly. Otherwise OkHttp
    will use reflection to extract the `TrustManager` from the
    `SSLSocketFactory`.
 *  New: Support prerelease Java 9. This gets ALPN from the platform rather than
    relying on the alpn-boot bootclasspath override.

With Kubernetes 1.15 as beta, OpenAPI schemas are also published for CRDs, as long as their schemas are structural.

These changes are reflected in the following Kubernetes enhancements:

- Kube-apiserver: timeouts configured for authorization webhooks in the --authorization-config file are now honored, and webhook timeouts are accurately reflected in webhook metrics with result=timeout ([#125552](https://github.com/kubernetes/kubernetes/pull/125552), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, Auth and Testing]

- K8s.io/apimachinery - scheme.Convert() now uses only explicitly registered conversions - default reflection based conversion is no longer available. `+k8s:conversion-gen` tags can be used with the `k8s.io/code-generator` component to generate conversions.

which becomes an attribute for all the fields in the corresponding
field declaration. An empty tag string is equivalent to an absent tag.
The tags are made visible through a <a href="/pkg/reflect/#StructTag">reflection interface</a>
and take part in <a href="#Type_identity">type identity</a> for structs
but are otherwise ignored.
