  Added PEP 3101.

  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.

  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.

  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)'.

  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.

  Try to make command line error messages from runpy easier to understand (and suppress traceback cruft from the implicitly invoked runpy machinery)
