Abstract

    This document describes the development and release schedule for
    Python 2.6.  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 release date is planned to be in XXX 2008.


Release Manager and Crew

    XXX volunteered to be Release Manager.

    XXX is building the Windows installers,
    XXX is building the Mac installers,
    XXX the doc packages and
    XXX the RPMs.


Release Schedule

    Note that this schedule is completely tentative. The number of alphas,
    betas and release candidates will be determined as the release process
    unfolds.  The minimal schedule is:

        June 2007:  (re)confirm the crew and start deciding on schedule.
                    The initial 2.6 target is for April 2008.

        alpha 1: T - 16 weeks [planned]
        alpha 2: T - 13 weeks [planned]
        beta 1:  T -  9 weeks [planned]
        beta 2:  T -  5 weeks [planned]
        rc 1:    T -  1 week  [planned]
        final:   T [planned]


Completed features for 2.6

    PEPs:

        None

    New modules in the standard library:

        None

    Other major features:

        None


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 possible inclusion in 2.6:

        - PEP 275:  Switching on Multiple Values
        - PEP 297:  Support for System Upgrades

    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)
        - turtle.py replacement or enhancements
        - adding a __dir__() magic method to control dir() [1]

    New modules in the standard library:

        - winerror
          http://python.org/sf/1505257
          (Owner: MAL)

        - setuptools

    - warnings module implemented in C

    - Add warnings for Py3k features removed:
      * backticks and <>
      * __getslice__/__setslice__/__delslice__
      * float args to PyArgs_ParseTuple
      * float args to xrange
      * coerce and all its friends
      * __cmp__?
      * other comparison changes?
      * int division?
      * {}.has_key()
      * All PendingDeprecationWarnings (e.g. exceptions)
      * using zip() result as a list
      * input()
      * apply()
      * xreadlines
      * function attributes that start with func_* (should use __*__)

    - with/as will be keywords

    - 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.

    - All of Python (including Modules/) should compile cleanly with g++

    - Start removing deprecated features and generally moving towards Py3k

    - Replace all old style tests (operate on import) with unittest or docttest

    - All tests for all untested modules

    - Document undocumented modules/features

    - bdist_deb in distutils package
      http://mail.python.org/pipermail/python-dev/2006-February/060926.html

    - bdist_egg in distutils package

    - pure python pgen module
      (Owner: Guido)
      Deferral to 2.6:
      http://mail.python.org/pipermail/python-dev/2006-April/064528.html

    - Remove the fpectl module?

    - Make everything in Modules/ build cleanly with g++

Deferred until 2.7

    None
