are now lazy wrappers over the underlying modules instead of the actual
modules themselves.

- Issue 49: Add six.moves mapping for tkinter.ttk.

variable.

a class.

respectively to itertools.izip_longest and itertools.ifilterfalse on Python 2
and itertools.zip_longest and itertools.filterfalse on Python 3.

- Issue 25: Add the unichr function, which returns a string for a Unicode
codepoint.

- Issue 26: Add byte2int function, which complements int2byte.

- Add a PY2 constant with obvious semantics.

- Add helpers for indexing and iterating over bytes: iterbytes and indexbytes.

- Add create_bound_method() wrapper.

- Issue 23: Allow multiple base classes to be passed to with_metaclass.

- Issue 24: Add six.moves.range alias. This exactly the same as the current
xrange alias.

- Pull request 5: Create six.moves.urllib, which contains abstractions for a
bunch of things which are in urllib in Python 3 and spread out across urllib,
urllib2, and urlparse in Python 2.```



### 1.3.0
```-----

- Issue 21: Add methods to access the closure and globals of a function.

- In six.iter(items/keys/values/lists), passed keyword arguments through to the
underlying method.

- Add six.iterlists().

- Issue 20: Fix tests if tkinter is not available.

in Python 3.2+.

keyword arguments will raise.

imported under.

- Fix Jython detection.

- Pull request 4: Add email_mime_multipart, email_mime_text, and
email_mime_base to six.moves.```



### 1.2.0
```-----

- Issue 13: Make iterkeys/itervalues/iteritems return iterators on Python 3
instead of iterables.

- Issue 11: Fix maxsize support on Jython.

- Add six.next() as an alias for six.advance_iterator().

- Use the builtin next() function for advance_iterator() where is available
(2.6+), not just Python 3.

- Add the Iterator class for writing portable iterators.```



### 1.1.0
```-----

- Add the int2byte function.

- Add compatibility mappings for iterators over the keys, values, and items of a
dictionary.

- Fix six.MAXSIZE on platforms where sizeof(long) != sizeof(Py_ssize_t).

- Issue 3: Add six.moves mappings for filter, map, and zip.```



### 1.0

are interested in an import compatibility layer.```
