******************************

* Calling the "__new__()" method of "struct.Struct" without the
  *format* argument is deprecated and will be removed in Python 3.20.
  Calling "__init__()" method on initialized "Struct" objects is
  deprecated and will be removed in Python 3.20.

* The "__version__", "version" and "VERSION" attributes have been
  deprecated in these standard library modules and will be removed in
  Python 3.20. Use "sys.version_info" instead.

  * "argparse"

  * "csv"

  * "ctypes"

  * "ctypes.macholib"

  * "decimal" (use "decimal.SPEC_VERSION" instead)

  * "http.server"

  * "imaplib"

  * "ipaddress"

  * "json"

  * "logging" ("__date__" also deprecated)

  * "optparse"

  * "pickle"

  * "platform"

  * "re"

  * "socketserver"

  * "tabnanny"

  * "tarfile"

  * "tkinter.font"

* Deprecations defined by **PEP 829**:

  * Warnings are produced for "import" lines found in "*name*.pth"
    files.

  * "*name*.pth" files are no longer decoded in the locale encoding by
    default.  They **MUST** be encoded in "utf-8-sig".

* "ast":

  * Creating instances of abstract AST nodes (such as "ast.AST" or
    "ast.expr") is deprecated and will raise an error in Python 3.20.

* "typing":

  * It is deprecated to call "isinstance()" and "issubclass()" checks
    on protocol classes that were not explicitly decorated with
    "runtime_checkable()" but that inherit from a runtime-checkable
    protocol class. This will raise a "TypeError" in Python 3.20.
