### SUMMARY
```
  sha256sum:
    description:
      - If a SHA-256 checksum is passed to this parameter, the digest of the
        destination file will be calculated after it is downloaded to ensure
        its integrity and verify that the transfer completed successfully.
        This option is deprecated. Use C(checksum) instead.
```

There is no `module.deprecate` either for `sha256sum`.

the argument has been declared deprecated in commit b3b11fbce26 (2017)

##### ISSUE TYPE
- Bug Report

##### COMPONENT NAME
get_url

* ansible version: 2.10

- From Ansible 2.4 when run with C(--check), it will do a HEAD request to validate the URL but
       will not download the entire file or verify it against hashes.
     - For Windows targets, use the M(win_get_url) module instead.
version_added: '0.6'
options:
  url:
    description:
      - HTTP, HTTPS, or FTP URL in the form (http|https|ftp)://[user[:pass]]@host.domain[:port]/path
    type: str
    required: true
  dest:
    description:
      - Absolute path of where to download the file to.
      - If C(dest) is a directory, either the server provided filename or, if
        none provided, the base name of the URL on the remote server will be
        used. If a directory, C(force) has no effect.
      - If C(dest) is a directory, the file will always be downloaded
        (regardless of the C(force) option), but replaced only if the contents changed..
    type: path
    required: true
  tmp_dest:
    description:
      - Absolute path of where temporary file is downloaded to.
      - When run on Ansible 2.5 or greater, path defaults to ansible's remote_tmp setting
      - When run on Ansible prior to 2.5, it defaults to C(TMPDIR), C(TEMP) or C(TMP) env variables or a platform specific value.
