Today the Xfce team released the first official pre-release build of what will later become Xfce version 4.8.
From the release announcement:
This release incorporates major changes to the core of the Xfce desktop environment and hopefully succeeds in fulfilling a number of long time requests. Among the most notable updates is that we have ported the entire Xfce core (Thunar, xfdesktop and thunar-volman in particular) from ThunarVFS to GIO, bringing remote filesystems to the Xfce desktop. The panel has been rewritten from scratch and provides better launcher management and improved multi-head support. The list of new panel features is too long to mention in its entirety here. Thanks to the new menu library garcon (formerly known as libxfce4menu, but rewritten once again) we now support menu editing via a third-party menu editor such as Alacarte (we do not ship our own yet). Our core libraries have been streamlined a bit, a good examplle being the newly introduced libxfce4ui library which is meant to replace libxfcegui4.
Perhaps the most important achievement we will accomplish with Xfce 4.8 is that, despite suffering from the small size of the development team from time to time, the core of the desktop environment has been aligned with today’s desktop technologies such as GIO, ConsoleKit, PolicyKit, udev and many more. A lot of old cruft has been stripped from the core as well, as has happened with HAL and ThunarVFS (which is still around for compatibility reasons).
There will be several additional pre-releases prior to the final release in January. Read the full release announcement (best viewed in Firefox) for more information about this particular pre-release build.
