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
|
||
http://python.org/sf/1505257
|
||
(Patch rejected, module should be written in C)
|
||
|
||
- setuptools
|
||

|
||
