Subject: RELEASED Python 2.5 (beta 2)
by Anthony Baxter July 11, 2006

July 11, 2006

On behalf of the Python development team and the Python community, I'm happy to announce the second BETA release of Python 2.5. This is an *beta* release of Python 2.5. As such, it is not suitable for a production environment. It is being released to solicit feedback and hopefully discover bugs, as well as allowing you to determine how changes in 2.5 might impact you. If you find things broken or incorrect, please log a bug on Sourceforge. In particular, note that changes to improve Python's support of 64 bit systems might require authors of C extensions to change their code. More information (as well as source distributions and Windows installers) are available from the 2.5 website: http://www.python.org/2.5/ A Universal Mac OSX Installer will be available shortly - in the meantime, Mac users can build from the source tarballs. Since the first beta, a large number of bug fixes have been made to Python 2.5 - see the release notes (available from the 2.5 webpage) for the full details. There has been one very small new feature added - the sys._current_frames() function was added. This is extremely useful for tracking down deadlocks and related problems - a similar technique is already used in the popular DeadlockDebugger extension for Zope. It is not possible to do this sort of debugging from outside the Python core safely and robustly, which is why we've snuck this in after the feature freeze. As of this release, Python 2.5 is now in *feature freeze*. Unless absolutely necessary, no functionality changes will be made between now and the final release of Python 2.5. The plan is for this to be the final beta release. We should now move to one or more release candidates, leading to a 2.5 final release early August. PEP 356 includes the schedule and will be updated as the schedule evolves. At this point, any testing you can do would be greatly, greatly appreciated. The new features in Python 2.5 are described in Andrew Kuchling's What's New In Python 2.5. It's available from the 2.5 web page. Amongst the language features added include conditional expressions, the with statement, the merge of try/except and try/finally into try/except/finally, enhancements to generators to produce a coroutine kind of functionality, and a brand new AST-based compiler implementation. New modules added include hashlib, ElementTree, sqlite3, wsgiref and ctypes. In addition, a new profiling module "cProfile" was added. Enjoy this new release, Anthony Anthony Baxter anthony(a)python.org Python Release Manager (on behalf of the entire python-dev team)

ANN: webstring 0.4 and lwebstring 0.4 released
by L. C. Rees July 10, 2006

July 10, 2006

webstring is an XML template engine that uses Python as its template language. It exposes the XML you need and hides the XML you don't. XML manipulation is done with Python so you don't have to learn a separate template language. webstring templates are plain XML or HTML so designers don't need to become programmers. webstring can take broken HTML and output it as HTML 4.01 or XHTML along with other XML formats. It can also act as WSGI middleware for templating web output on the fly. webstring uses cElementTree or elementtree as its XML processing backend. lwebstring uses lxml, a Python binding for the libxml2 and libxsl libraries. Highlights of release 0.4 of webstring and lwebstring include: - Output changes: fields and groups output a marked element, its children, and new siblings instead of the marked element's parent element when rendered as a string. - Template concatenation can be chained i.e. template1 + template2 + template3 - includes middleware for using the Template and HTMLTemplate classes with WSGI applications. Highlights of release 0.4 of lwebstring include: - can apply XSLT stylesheets to a Template using the "transform" method

ANN: MoinMoin 1.5.4 (advanced wiki engine) released
by Alexander Schremmer July 8, 2006

July 8, 2006

_ _ /\/\ ___ (_)_ __ /\/\ ___ (_)_ __ / \ / _ \| | '_ \ / \ / _ \| | '_ \ __ / /\/\ \ (_) | | | | / /\/\ \ (_) | | | | | /| |_ \/ \/\___/|_|_| |_\/ \/\___/|_|_| |_| |.__) ============================================== MoinMoin 1.5.4 advanced wiki engine released ============================================== MoinMoin is an easy to use, full-featured and extensible wiki software package written in Python. It can fulfill a wide range of roles, such as a personal notes organizer deployed on a laptop or home web server, a company knowledge base deployed on an intranet, or an Internet server open to individuals sharing the same interests, goals or projects. A wiki is a collaborative hypertext environment with an emphasis on easy manipulation of information. MoinMoin 1.5.4 is a bug fix release and a recommended update. The 1.5 branch brings you several new features such as the GUI editor, which allows the users to edit pages in a WYSIWYG environment, and many bug fixes. The download page: http://moinmoin.wikiwikiweb.de/MoinMoinDownload New features in 1.5.4 ===================== * Fixes in the GUI editor. * Dashes in the username were allowed. * EmbedObject macro for embedding of all kinds of multimedia formats into the page. * Speedup of the Twisted adapter. Major bug fixes in 1.5.4 ======================== * Many GUI editor related bug fixes. * Increased docutils compatiblity. Major new features in 1.5 ========================= * The WYSIWYG editor for wiki pages allows you to edit pages without touching the markup. Furthermore, the wiki page is not stored as HTML after editing but kept as wiki markup in order to simplify the editing process for users that cannot or do not want to use the new editor. * AutoAdmin security policy allows users to gain admin permissions on particular pages. * The new authentication system allows to add short methods that check the credentials of the user. This allowed us to add eGroupware single sign on support. * Separation of homepages into a separate wiki (in a farm) and having a single user database is supported. * A DeSpam action to allow mass-reverting of spam attacks. * PackageInstaller support for simplified installation of plugins, themes and page bundles. This enables you to decide in which languages help pages should be installed. Note that Python 2.3.0 or newer is required. For a more detailed list of changes, see the CHANGES file in the distribution or http://moinmoin.wikiwikiweb.de/MoinMoinRelease1.5/CHANGES MoinMoin History ================ MoinMoin has been around since year 2000. The codebase was initally started by Jürgen Hermann; it is currently being developed by a growing team. Being originally based on PikiPiki, it has evolved heavily since then (PikiPiki and MoinMoin 0.1 consisted of just one file!). Many large enterprises have been using MoinMoin as a key tool of their intranet, some even use it for their public web page. A large number of Open Source projects use MoinMoin for communication and documentation. Of course there are also many private installations.

[ANNOUNCE] Thirty-third release of PythonCAD now available
by Art Haas July 7, 2006

July 7, 2006

Hi. I'm pleased to announce the thirty-third development release of PythonCAD, a CAD package for open-source software users. As the name implies, PythonCAD is written entirely in Python. The goal of this project is to create a fully scriptable drafting program that will match and eventually exceed features found in commercial CAD software. PythonCAD is released under the GNU Public License (GPL). PythonCAD requires Python 2.2 or newer. The interface is GTK 2.0 based, and uses the PyGTK module for interfacing to GTK. The design of PythonCAD is built around the idea of separating the interface from the back end as much as possible. By doing this, it is hoped that both GNOME and KDE interfaces can be added to PythonCAD through usage of the appropriate Python module. Addition of other PythonCAD interfaces will depend on the availability of a Python module for that particular interface and developer interest and action. The thirty-third release contains several major updates to the program. Drawing operations have been greatly sped up when entities are added to a drawing, modified, or deleted from a drawing. Users on older hardware or machines with slower video systems will notice this change immediately. A second large change in this release is the completion of separating the interface code from the core code by using the internal messaging system in place of object inheritance. The third big change in this release is the formatting of the interface text strings for internationalization, and a Spanish translation is now available for users to install. It is hoped that more translations appear in future releases. Additionally, a large number of smaller improvements, enhancements, and bug fixes are also present in this release. A mailing list for the development and use of PythonCAD is available. Visit the following page for information about subscribing and viewing the mailing list archive: http://mail.python.org/mailman/listinfo/pythoncad Visit the PythonCAD web site for more information about what PythonCAD does and aims to be: http://www.pythoncad.org/ Come and join me in developing PythonCAD into a world class drafting program! Art Haas -- Man once surrendering his reason, has no remaining guard against absurdities the most monstrous, and like a ship without rudder, is the sport of every wind. -Thomas Jefferson to James Smith, 1822
