  r60901 | eric.smith | 2008-02-19 14:21:56 +0100 (Tue, 19 Feb 2008) | 1 line

  Added PEP 3101.
........
  r60907 | georg.brandl | 2008-02-20 20:12:36 +0100 (Wed, 20 Feb 2008) | 2 lines

  Fixes contributed by Ori Avtalion.
........
  r60909 | eric.smith | 2008-02-21 00:34:22 +0100 (Thu, 21 Feb 2008) | 1 line

  Trim leading zeros from a floating point exponent, per C99.  See issue 1600.  As far as I know, this only affects Windows.  Add float type 'n' to PyOS_ascii_formatd (see PEP 3101 for 'n' description).
........
  r60910 | eric.smith | 2008-02-21 00:39:28 +0100 (Thu, 21 Feb 2008) | 1 line

  Now that PyOS_ascii_formatd supports the 'n' format, simplify the float formatting code to just call it.
........
  r60918 | andrew.kuchling | 2008-02-21 15:23:38 +0100 (Thu, 21 Feb 2008) | 2 lines

  Close manifest file.
  This change doesn't make any difference to CPython, but is a necessary fix for Jython.
........
  r60921 | guido.van.rossum | 2008-02-21 18:46:16 +0100 (Thu, 21 Feb 2008) | 2 lines

  Remove news about float repr() -- issue 1580 is still in limbo.
........
  r60923 | guido.van.rossum | 2008-02-21 19:18:37 +0100 (Thu, 21 Feb 2008) | 5 lines

  Removed uses of dict.has_key() from distutils, and uses of
  callable() from copy_reg.py, so the interpreter now starts up
  without warnings when '-3' is given.  More work like this needs to
  be done in the rest of the stdlib.
........
  r60924 | thomas.heller | 2008-02-21 19:28:48 +0100 (Thu, 21 Feb 2008) | 4 lines

  configure.ac: Remove the configure check for _Bool, it is already done in the
  top-level Python configure script.
  configure, fficonfig.h.in: regenerated.
........
  r60925 | thomas.heller | 2008-02-21 19:52:20 +0100 (Thu, 21 Feb 2008) | 3 lines

  Replace 'has_key()' with 'in'.
  Replace 'raise Error, stuff' with 'raise Error(stuff)'.
........
  r60927 | raymond.hettinger | 2008-02-21 20:24:53 +0100 (Thu, 21 Feb 2008) | 1 line

  Update more instances of has_key().
........
  r60928 | guido.van.rossum | 2008-02-21 20:46:35 +0100 (Thu, 21 Feb 2008) | 3 lines

  Fix a few typos and layout glitches (more work is needed).
  Move 2.5 news to Misc/HISTORY.
........
  r60936 | georg.brandl | 2008-02-21 21:33:38 +0100 (Thu, 21 Feb 2008) | 2 lines

  #2079: typo in userdict docs.
........
  r60938 | georg.brandl | 2008-02-21 21:38:13 +0100 (Thu, 21 Feb 2008) | 2 lines

  Part of #2154: minimal syntax fixes in doc example snippets.
........
  r60942 | raymond.hettinger | 2008-02-22 04:16:42 +0100 (Fri, 22 Feb 2008) | 1 line

  First draft for itertools.product().  Docs and other updates forthcoming.
........
  r60955 | nick.coghlan | 2008-02-22 11:54:06 +0100 (Fri, 22 Feb 2008) | 1 line

  Try to make command line error messages from runpy easier to understand (and suppress traceback cruft from the implicitly invoked runpy machinery)
........
  r60956 | georg.brandl | 2008-02-22 13:31:45 +0100 (Fri, 22 Feb 2008) | 2 lines

  A lot more typo fixes by Ori Avtalion.
........
  r60957 | georg.brandl | 2008-02-22 13:56:34 +0100 (Fri, 22 Feb 2008) | 2 lines

  Don't reference pyshell.
........
  r60958 | georg.brandl | 2008-02-22 13:57:05 +0100 (Fri, 22 Feb 2008) | 2 lines

  Another fix.
