XCB: the X Protocol C Binding
The XCB project aims to replace the Xlib interface to the X Window System:
The X protocol C-language Binding (XCB) is a replacement for Xlib featuring a small footprint, latency hiding, direct access to the protocol, improved threading support, and extensibility.
Bart Massey and Jamey Sharp originally described XCB in a 2001 paper entitled: An X Protocol C Binding [PDF]. The XCB project history gives a look at some important project milestones and lists the tasks that have been completed to date.
The XCB project aims to improve on a number of Xlib weaknesses. Some of the XCB features include:
- A smaller memory footprint than Xlib.
- Support for latency hiding to address Xlib speed issues.
- Support for partial emulation of the Xlib API.
- Support for direct access to the X protocol.
- Support for the addition of new X extensions.
- Thread support designed from the beginning, not added-on like Xlib.
- Built on top of an XML description (xcb-proto) of the core X protocol.
- Development of the Xlib Compatibility Layer (XCL) for running legacy applications.
We have provided this candidate release to allow for more widespread
review and testing before XCB 1.0. As of version 1.0, libxcb will
provide a stable API and ABI; future changes will consist only of
additions, and applications compiled against XCB 1.0 or newer will work
with all future versions of XCB. Barring discovery of serious issues
with the API, we do not anticipate any API changes between this release
and the 1.0 release.
We would greatly appreciate API review in this final release candidate
period.
Other changes in this release include: a new API naming convention, new include directory conventions, an improved error handling plan, a more resilient connection error handling system, removal of deprecated functions, a split of the GIT repository, and bug fixes.
For more information on XCB, see the XCB API definition, the XCB Tutorial, the XCB Developer's Guide and other publications on XCB.

Zope 3.3.0 released

Zope 3 is the next major Zope release and has been written from scratch based on the latest software design patterns and the experiences of Zope 2. Cleanup of the Zope 3 packages has continued to ensure a flexible and scalable platform. We continued the work on making the transition from Zope 2 to Zope 3 by making Zope 2.10 use even more of the Zope 3 packages. But the transition is far from complete yet."

Desktop Environments
Plans for gnome-vfs replacement (GnomeDesktop)
GnomeDesktop follows a thread by Alexander Larsson concerning a gnome-vfs overhaul. "Recently there has been a lot of discussions about the gnome platform and the correct stacking order and quality of the modules. Gnome-vfs is a clear problem in this discussion. Having spent the last 4 years as the gnome-vfs maintainer, and even longer as the primary gnome-vfs user (in Nautilus) I'm well aware of the problems it has. I think that we've reached a point where the problems in the gnome-vfs architecture and its position in the stack are now ranking as one of the most problematic aspects of the gnome platform, especially considering the enhancements and quality improvements seen in other parts of the platform."
