#### What is OpenAPI for { #what-is-openapi-for }

The OpenAPI schema is what powers the two interactive documentation systems included.

And there are dozens of alternatives, all based on OpenAPI. You could easily add any of those alternatives to your application built with **FastAPI**.

And then the new OpenAPI 3.1.0 was based on the latest version (JSON Schema 2020-12) that included this new field `examples`.

And now this new `examples` field takes precedence over the old single (and custom) `example` field, that is now deprecated.

### PodSecurity graduates to Beta

[PodSecurity](https://kubernetes.io/docs/concepts/security/pod-security-admission/) moves to Beta.
`PodSecurity` replaces the deprecated `PodSecurityPolicy` admission controller.

//     specify a different capacity; it must be no smaller than the
//     length. For example, make([]int, 0, 10) allocates an underlying array
//     of size 10 and returns a slice of length 0 and capacity 10 that is
//     backed by this underlying array.
//   - Map: An empty map is allocated with enough space to hold the
//     specified number of elements. The size may be omitted, in which case
//     a small starting size is allocated.
