On behalf of the Python development team, I'm elated to announce the second beta
release of Python 2.7.
Python 2.7 is scheduled (by Guido and Python-dev) to be the last major version
in the 2.x series. 2.7 will have an extended period of bugfix maintenance.
2.7 includes many features that were first released in Python 3.1. The faster
io module, the new nested with statement syntax, improved float repr, set
literals, dictionary views, and the memoryview object have been backported from
3.1. Other features include an ordered dictionary implementation, unittests
improvements, a new sysconfig module, and support for ttk Tile in Tkinter. For
a more extensive list of changes in 2.7, see
http://doc.python.org/dev/whatsnew/2.7.html or Misc/NEWS in the Python
distribution.
To download Python 2.7 visit:
http://www.python.org/download/releases/2.7/
While this is a development release and is thus not suitable for production use,
we encourage Python application and library developers to test the release with
their code and report any bugs they encounter to:
http://bugs.python.org/
2.7 documentation can be found at:
http://docs.python.org/2.7/
Enjoy!

Pyspread 0.1.1 released
=======================
I am pleased to announce the new release 0.1.1 of pyspread.
About:
------
Pyspread is a cross-platform Python spreadsheet application.
It is based on and written in the programming language Python.
Instead of spreadsheet formulas, Python expressions are entered into
the spreadsheet cells. Each expression returns a Python object that can
be accessed from other cells. These objects can represent anything
including lists or matrices.
Pyspread runs on Linux and *nix platforms with GTK support as well as
on Windows (XP and Vista tested). On Mac OS X, some icons are too small
but the application basically works.

Changes to 0.1
--------------
* Grid is faster.
* Copying only partly filled cells works now.
* Cells that get attributes but no string no longer display None.
Enjoy

Embedding Python into your Qt / C++ application and accessing the
whole Qt API from within your Python scripts is right at your hands
with the new PythonQt 2.0 release.
http://pythonqt.sourceforge.net/
PythonQt consists of a small dynamic library that offers scripting
QObjects and interaction between
Qt and Python in both directions, mostly in the spirit of QtScript,
but for Python.
In addition to that, the core library can be extended using the new
wrapper generator to support raw C++ classes.
PythonQt comes with pregenerated wrappers for most Qt modules.
Note: The focus of PythonQt is embedding Python into your existing Qt
application (to make some aspects of it scriptable), and not to create
the whole application in Python. If you are looking for that, go for
PyQt or PySide!
The main features of this update are:
- a new wrapper generator (based on the qtscript generator) that
generates Python wrappers for (almost) the complete Qt framework
- support for multiple inheritance of wrapped C++ classes
- support for polymorphic downcast (e.g., QEvent will get its derived
type based on the type id)
- dynamic property support (both setting and getting via normal python
attributes)
- public member variable wrapping (for QStyleOptions and derived classes)
- full support for operators (so that QPoint, QSize etc. can be used
with operators in Python)
- automatic casting for special classes (QPen/QBrush/GlobalColor enum/...)
- deriving C++ objects from Python to implement virtual functions
(experimental feature)
With this release, the feature set of PythonQt comes much closer to
what PyQt and PySide offer, it is now
possible to create complex GUIs using PythonQt and you could delegate
large parts of your C++ application
to Python scripting (e.g., to let users customize the GUI, to support
Python plugins in your application, your idea goes here...).

Florian

* Tight integration with python run–time system — most of the
settings can be changed "on the fly" using management console.
* Powerful configuration system - define own actions, aliases,
internal commands, key bindings.
* Extensible plug-in system - even core functionality implemented
mainly using plug–ins, keeping base system small and clean.
* Events & hooks subsystem - a flexible way of reacting on certain
system events.
* Customizable look-n-feel - every widget component look can be
changed using skins.
* Unicode support

Hi All,
Pydev 1.5.7 has been released
Details on Pydev: http://pydev.org
Details on its development: http://pydev.blogspot.com
Release Highlights:
-------------------------------
* **Uniquely identifying editors:**
* Names are never duplicated
* Special treatment for __init__
* Special treatment for django on views, models and tests
* See: http://pydev.blogspot.com/2010/04/identifying-your-editors.html
for details
* **Debugger:**
* **CRITICAL**: Fixed issue which could make the debugger skip breakpoints
* Properly dealing with varibles that have '<' or '>'
* Debugging file in python 3 with an encoding works
* Double-clicking breakpoint opens file from the workspace instead
of always forcing an external file
* Added '* any file' option for file selection during a debug
where the file is not found
* **Performance improvements for dealing with really large files:**
* Code folding marks won't be shown on *really large files* for
performance reasons
* Performance improvements in the code-analysis (much faster for
*really large files*)
* Outline tree is also faster
* **Interpreter configuration:**
* Only restoring the needed interpreter info (so, it's much faster
to add a new interpreter)
* Using an asynchronous progress monitor (which makes it even faster)
* Interpreter location may not be duplicated (for cases where the
same interpreter is used with a different config, virtualenv should be
used)
* Properly refreshing internal caches (which made a ctrl+2+kill or
a restart of eclipse needed sometimes after configuring the
interpreter)
* socket added to forced builtins
* **Python 3 grammar:**
* Code completion and code-analysis work when dealing with keyword
only parameters
* Properly reporting syntax error instead of throwing a
NumberFormatException on "1.0L"
* **Editor and forcing tabs:**
* Option to toggle forcing tabs added to the editor context menu
* Fixed tabs issue which could change the global setting on force tabs
* **Indentation:**
* Added rule so that indentation stops at the level of the next
line def or @ (to indent to add a decorator)
* Auto indent strategy may indent based on next line if the
previous is empty
* **General:**
* Django configuration supporting version 1.2 (contribution by
Kenneth Belitzky)
* Fixed encoding problem when pasting encoded text with indentation
* asthelper.completions no longer created on current directory
when project is removed
* __all__ semantics correct when a tuple is defined (and not only
when a list is defined)
* Fixed issue in extract method (was not creating tuple on caller
function with multiple returns)
* Improved heuristic for assist assign (ctrl+1)
* On search open files (ctrl+2+s), dialog is opened if nothing is
entered and there's no editor selection
* Fixed issue where ctrl+2 would not work on linux
What is PyDev?
---------------------------
PyDev is a plugin that enables users to use Eclipse for Python, Jython
and IronPython development -- making Eclipse a first class Python IDE
-- It comes with many goodies such as code completion, syntax
highlighting, syntax analysis, refactor, debug and many others.
Cheers,

pytest-xdist 1.2 brings bug fixes and improved stability for distributed testing
with py.test. This plugin allows to ad-hoc distribute test runs to multiple
CPUs, different Python interpreters or remote machines. It requires setuptools
or distribute which help to pull in the neccessary execnet and pytest-core
dependencies.
See here for extensive docs: http://pytest.org/plugin/xdist.html
