# About FastAPI versions { #about-fastapi-versions }

**FastAPI** is already being used in production in many applications and systems. And the test coverage is kept at 100%. But its development is still moving quickly.

New features are added frequently, bugs are fixed regularly, and the code is still continuously improving.

## Deprecate a *path operation* { #deprecate-a-path-operation }

If you need to mark a *path operation* as <dfn title="obsolete, recommended not to use it">deprecated</dfn>, but without removing it, pass the parameter `deprecated`:

You may also setup etcd with TLS following this documentation [here](https://coreos.com/etcd/docs/latest/op-guide/security.html)

### 3. Setup MinIO with etcd

MinIO server expects environment variable for etcd as `MINIO_ETCD_ENDPOINTS`, this environment variable takes many comma separated entries.

```
export MINIO_ETCD_ENDPOINTS=http://localhost:2379

			return osErrToFileErr(err)
		}
		// There may be permission error when dirPath
		// is at the root of the disk mount that may
		// not have the permissions to avoid 'noatime'
		fd, err = openFileWithFD(dirPath, os.O_RDONLY, 0o666)
		if err != nil {
			if osErrToFileErr(err) == errFileNotFound {
