On behalf of the Python development team, I'm sanguine to announce a release
candidate for the fourth bugfix release for the Python 3.1 series, Python 3.1.4.

Since the 3.1.4 release candidate 2 weeks ago, there have been three changes:
1. test_zipfile has been fixed on systems with an ASCII filesystem
encoding. 2. pyexpat.__version__ has be changed to be the Python version. 3. A
regression from 2.7.1 in the handling of comments in the netrc module has been
resolved. (see issue #12009).

3.1.4 will the last bug fix release in the 3.1 series before 3.1. After 3.1.4,
3.1 will be in security-only fix mode.

The Python 3.1 version series focuses on the stabilization and optimization of
the features and changes that Python 3.0 introduced.  For example, the new I/O
system has been rewritten in C for speed.  File system APIs that use unicode
strings now handle paths with undecodable bytes in them. Other features include
an ordered dictionary implementation, a condensed syntax for nested with
statements, and support for ttk Tile in Tkinter.  For a more extensive list of
changes in 3.1, see http://doc.python.org/3.1/whatsnew/3.1.html or Misc/NEWS in
the Python distribution.
