The meaning of "full-stack" is somewhat in the eye of the beholder, of course. But by most standards, TG does a good job of providing for all tiers of a typical Web application. Its major components are:
The templating systems are also significantly different: Kid templates consist of well-formed XML (often XHTML in practice) with Python embedded in attributes and element content, while Rails uses Embedded Ruby (ERuby), which uses non-XML tags to embed Ruby in (X)HTML or other text files.
One of the most important differences, however, is in the ORM layer: the ActiveRecord package used in Rails provides an object layer over an existing database, whereas Python's SQLObject also allows the database to be generated based on Python objects.
This is not to suggest that TG is superior in every respect. Rails has a "scaffolding" feature, which automatically generates CRUD (Create, Retrieve, Update, Delete) operations. There is also an ActionMailer package which provides e-mail services for applications. In other words, while TurboGears and Rails have many similarities, they are far from identical.
Beyond the differences in features, there remains the highly subjective matter of language choice. Even if TG were simply a clone of Rails, surely it is a wonderful thing that developers can implement architectures in the language of their choice. Isn't that what open source is all about? And the community appears to have ample energy for creating and maintaining Web frameworks.
To my mind, what really stands out about TG is the clear vision and the sense of competence that its developers are communicating. There are many technically sound and interesting Web tools available, but they often suffer from poor documentation and worse marketing. While its feature set is highly attractive in itself, it is the project's superior presentation that makes it likely to attract a broad following.
Database Softwarewhat's new page has more information. This is a bugfix release for the current production version." is available for testing.
Librarieshas been announced. "EasyBMP is an easy cross-platform C++ library for reading and writing Windows bitmap (BMP) files. No installation, no need for external libraries, small in size, well-documented, and simple enough for the novice programmer to start in just minutes! EasyBMP particularly shines as an easy image input/output tool for scientists and other technically-minded people who may not be formally trained in programming". Changes include bug fixes, a change to the revised BSD license, and more.
Web Site Developmenthas been announced. "PHPSurveyor 0.99 is the culmination of 12 months of development and bugfixing for PHPSurveyor since the "stable" release of 0.98. The package has undergone significant changes and enchancements, however - importantly - can still be installed over the top of most existing 0.98final installations and upgraded without losing data. This is labelled a "stable" release, indicating that the recent months have been dedicated to bugfixing rather than the development of new features." has been released. "We are pleased to announce that our release candidate for the Xaraya 1.0.0 web application framework is now available. This release candidate addresses compatibility issues with php versions 4.4 and some 5.1 versions, as well as important bug fixes." discusses the process of finding security vulnerabilities in web applications in an O'Reilly article. "The nature of web applications is very different from that of standard applications. Many times, these tools miss key vulnerabilities in the application. The best way to perform web application assessment is by using the unassailable combination of automated tools and human intellect. This article examines the LiveHTTPHeaders project, which fits seamlessly into Mozilla browser components to facilitate very effective web application assessment."
Web Servicesworks with the Globus Toolkit on O'Reilly. "Grid computing allows you to combine processing, storage, databases, and other resources across a network, hiding the details from callers.

More of the menus can be activated from the keyboard, and stretch/move operations now accept entry box values when performing either task. A significant amount of work has been applied to the internal routines used for storing the entities in a drawing, the result of which required numerous changes throughout the code."
Calendar Softwareare available for testing. Dan Mosedale's blog has more information on the software: "Thanks to the magic of Chase and Coop, there are now nightly builds of Lightning for all three platforms. Note that these are not quite ready for day-to-day use yet (there are still known dataloss bugs, UI issues, and crashers). However, if you'd like to play around, help us test, give UI suggestions, or have a taste for getting involved in the development, this is a great way to get started."
Data Visualizationhas been announced. "Veusz is a scientific plotting package written in Python (currently 100% Python). It uses PyQt for display and user-interfaces, and numarray for handling the numeric data. Veusz is designed to produce publication-ready Postscript output."

"Have you ever renamed 768 files? Merged the content from 96 files into a spreadsheet? Filtered 100 lines out of a 20,000-line file? Have you ever done these things by hand? Disciples of laziness--one of the three Perl programmer's virtues--know that you should never repeat anything five times, let alone 768. It dismayed me to learn that biologists do this kind of thing all the time."

Web Browsersa report from the GNOME summit on the future of the Galeon browser.
