# What’s New

## What’s new in version 0.15.2 (2015-09-11)

This is a minor bug-fix release:

- Fix `socket.create_connection()` backport on Py2.6 (issue #162)
- Add more tests of `urllib.request` etc.
- Fix `newsuper()` calls from the `__init__` method of PyQt subclassses (issue #160, thanks to Christopher Arndt)

## What’s new in version 0.15.1 (2015-09-09)

This is a minor bug-fix release:

- Use 3-argument `socket.create_connection()` backport to restore Py2.6 compatibility in `urllib.request.urlopen()` (issue #162)
- Remove breakpoint in `future.backports.http.client` triggered on certain data (issue #164)
- Move `exec` fixer to stage 1 of `futurize` because the forward-compatible `exec(a, b)` idiom is supported in Python 2.6 and 2.7. See https://docs.python.org/2/reference/simple_stmts.html#exec.

## What’s new in version 0.15.0 (2015-07-25)

This release fixes compatibility bugs with CherryPy’s Py2/3 compat layer and the latest version of the `urllib3` package. It also adds some additional backports for Py2.6 and Py2.7 from Py3.4’s standard library.

New features:

- `install_aliases()` now exposes full backports of the Py3 urllib submodules (`parse`, `request` etc.) from `future.backports.urllib` as submodules of `urllib` on Py2. This implies, for example, that `urllib.parse.unquote` now takes an optional encoding argument as it does on Py3. This improves compatibility with CherryPy’s Py2/3 compat layer (issue #158).
- `tkinter.ttk` support (issue #151)
- Backport of `collections.ChainMap` (issue #150)
- Backport of `itertools.count` for Py2.6 (issue #152)
- Enable and document support for the `surrogateescape` error handler for `newstr` and `newbytes` objects on Py2.x (issue #116). This feature is currently in alpha.
- Add constants to `http.client` such as `HTTP_PORT` and `BAD_REQUEST` (issue #137)
- Backport of `reprlib.recursive_repr` to Py2

Bug fixes:

- Add `HTTPMessage` to `http.client`, which is missing from `httplib.__all__` on Python <= 2.7.10. This restores compatibility with the latest `urllib3` package (issue #159, thanks to Waldemar Kornewald)
- Expand newint.__divmod__ and newint.__rdivmod__ to fall back to <type ‘long’> implementations where appropriate (issue #146 - thanks to Matt Bogosian)
- Fix newrange slicing for some slice/range combos (issue #132, thanks to Brad Walker)
- Small doc fixes (thanks to Michael Joseph and Tim Tröndle)
- Improve robustness of test suite against opening .pyc files as text on Py2
- Update backports of `Counter` and `OrderedDict` to use the newer implementations from Py3.4. This fixes `.copy()` preserving subclasses etc.
- `futurize` no longer breaks working Py2 code by changing `basestring` to `str`. Instead it imports the `basestring` forward-port from `past.builtins` (issues #127 and #156)
- `future.utils`: add `string_types` etc. and update docs (issue #126)
