Abstract
|
|
========
|
|
|
|
This document describes the development and release schedule for
|
|
Python 2.6 and 3.0. The schedule primarily concerns itself with
|
|
PEP-sized items. Small features may be added up to and including
|
|
the first beta release. Bugs may be fixed until the final
|
|
release.
|
|
|
|
There will be at least two alpha releases, two beta releases, and
|
|
one release candidate. The releases are planned for October 2008.
|
|
|
|
Python 2.6 is not only the next advancement in the Python 2
|
|
series, it is also a transitional release, helping developers
|
|
begin to prepare their code for Python 3.0. As such, many
|
|
features are being backported from Python 3.0 to 2.6. Thus, it
|
|
makes sense to release both versions in at the same time. The
|
|
precedence for this was set with the Python 1.6 and 2.0 release.
|
|
|
|
Until rc, we will be releasing Python 2.6 and 3.0 in lockstep, on
|
|
a monthly release cycle. The releases will happen on the first
|
|
Wednesday of every month through the beta testing cycle. Because
|
|
Python 2.6 is ready sooner, and because we have outside deadlines
|
|
we'd like to meet, we've decided to split the rc releases. Thus
|
|
Python 2.6 final is currently planned to come out two weeks before
|
|
Python 3.0 final.

Possible features for 2.6
|
|
=========================
|
|
|
|
New features *should* be implemented prior to alpha2, particularly
|
|
any C modifications or behavioral changes. New features *must* be
|
|
implemented prior to beta1 or will require Release Manager approval.
|
|
|
|
The following PEPs are being worked on for inclusion in 2.6: None.
|
|
|
|
Each non-trivial feature listed here that is not a PEP must be
|
|
discussed on python-dev. Other enhancements include:
|
|
|
|
- ``distutils`` replacement (requires a PEP)
|
|
|
|
New modules in the standard library:
|
|
|
|
- ``winerror``
|
|
https://bugs.python.org/issue1505257
|
|
(Patch rejected, module should be written in C)
|
|
|
|
- ``setuptools``
|

|
|
or through negligence):
|
|
|
|
- ``rfc822``
|
|
- ``mimetools``
|
|
- ``multifile``
|
|

|
|
|
* ``__getslice__``/``__setslice__``/``__delslice__``
|
|
|
|
* float args to ``PyArgs_ParseTuple``
|
|

|
* using ``zip()`` result as a list
|
|

|
|

|
|
|
|
- use ``__bool__`` method if available and there's no ``__nonzero__``
|
|
|
|
- Check the various bits of code in ``Demo/`` and ``Tools/`` all still work,
|
|
update or remove the ones that don't.
|
|
|
|
- All modules in ``Modules/`` should be updated to be ``ssize_t`` clean.
|
|
|
|

|
|
|
|

|
|

|
|
|
|
- Add tests for all untested modules
|
|
|
|
- Document undocumented modules/features
|
|
|
|
