### Bug Fixes and Other Changes

*   `tf.Variable`

    *   Changed resource variables to inherit from `tf.compat.v2.Variable` instead of `tf.compat.v1.Variable`. Some checks for `isinstance(v, tf compat.v1.Variable)` that previously returned True may now return False.

*   `tf.distribute`

 * <p>
 * Supported OS families include:
 * <ul>
 * <li>windows: All Windows variants</li>
 * <li>win9x: Windows 95, 98, ME, CE</li>
 * <li>winnt: Windows NT variants</li>
 * <li>unix: Unix-like systems (including Linux)</li>
 * <li>mac: macOS (including Darwin)</li>
 * <li>os/2: OS/2 variants</li>
 * <li>netware: Novell NetWare</li>
 * <li>dos: DOS variants</li>
 * <li>tandem: Tandem systems</li>
 * <li>openvms: OpenVMS</li>

Cuando instalas Python, se te podría preguntar si deseas actualizar la variable de entorno `PATH`.

//// tab | Linux, macOS

Digamos que instalas Python y termina en un directorio `/opt/custompython/bin`.

Si dices que sí para actualizar la variable de entorno `PATH`, entonces el instalador añadirá `/opt/custompython/bin` a la variable de entorno `PATH`.

Podría verse así:

```plaintext

The value of the variable `PATH` is a long string that is made of directories separated by a colon `:` on Linux and macOS, and by a semicolon `;` on Windows.

For example, the `PATH` environment variable could look like this:

//// tab | Linux, macOS

```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
```

### Classes en tant que types

Vous pouvez aussi déclarer une classe comme type d'une variable.

Disons que vous avez une classe `Person`, avec une variable `name` :

{*../../docs_src/python_types/tutorial010.py hl[1:3] *}


Vous pouvez ensuite déclarer une variable de type `Person` :

{*../../docs_src/python_types/tutorial010.py hl[6] *}

        checkArgument(!variable.equalsType(type), "Type variable %s bound to itself", variable);
        builder.put(variable, type);
      }
      return new TypeTable(builder.buildOrThrow());
    }

    final Type resolve(TypeVariable<?> var) {
      TypeTable unguarded = this;
      TypeTable guarded =
          new TypeTable() {
            @Override
