Olivier Fourdan started the Xfce project in late 1996 as a
Linux version of the
Common Desktop Environment (CDE), a
Unix desktop environment that was initially
proprietary and later released as
free software. The name was originally written as XFce, as an abbreviation of XForms Common Environment, which referred to the
XForms library. However, over time, Xfce diverged from CDE and now stands on its own. The
Slackware Linux distribution has nicknamed Xfce the "Cholesterol Free Desktop Environment", a loose interpretation of the initialism.
Mascot Per the FAQ, the logo of Xfce is "a mouse, obviously, for all kinds of reasons like world domination and monsters and such."
Early versions Xfce began as a simple project created with XForms.
Olivier Fourdan released the program, which was just a simple
taskbar, on
SunSITE. Fourdan continued developing the project and in 1998, Xfce 2 was released with the first version of Xfce's window manager, Xfwm. He requested the project be included in
Red Hat Linux, but it was refused due to its XForms basis. Red Hat accepted only open-source software released under a
GPL- or BSD-compatible license, whereas, at the time, XForms was closed-source and free only for personal use. In March 1999, Fourdan began a complete rewrite of the project based on
GTK, a non-proprietary toolkit then rising in popularity. The result was Xfce 3.0, licensed under the GPL. As well as being based completely on
free software, it gained GTK
drag-and-drop support, native language support, and improved configurability. Xfce was uploaded to
SourceForge.net in February 2001, starting with version 3.8.1.
Xfce 4.0 - 4.10 s behind windows,
alpha-blended windows and panel In version 4.0.0, released 25 September 2003, Xfce was upgraded to use the
GTK 2 libraries. Changes in 4.2.0, released 16 January 2005, included a
compositing manager for Xfwm which added built-in support for transparency and drop shadows, as well as a new default
SVG icon set. In January 2007, Xfce 4.4.0 was released. This included the
Thunar file manager, a replacement for Xffm. Support for desktop icons was added. Also, various improvements were made to the panel to prevent buggy plugins from crashing the whole panel, as well as support for multiple panels; previous versions of Xfce could only support one panel in addition to Xftaskbar4 and Xfce4-iconbox. These tools were made available as panel plugins in this version. In February 2009, Xfce 4.6.0 was released. This version had a new configuration backend, a new settings manager and a new sound mixer, as well as several significant improvements to the session manager and the rest of Xfce's core components. In January 2011, Xfce 4.8.0 was released. This version included changes such as the replacement of ThunarVFS and
HAL with
GIO,
udev, ConsoleKit and
PolicyKit, and new utilities for browsing remote
network shares using several protocols including
SFTP,
SMB, and
FTP. Window clutter was reduced by merging all Thunar file progress
dialog boxes into a single dialog. The panel application was also rewritten for better positioning, transparency, and item and launcher management. 4.8 also introduced a new menu plugin to view directories. The 4.8 plugin framework remains compatible with 4.6 plugins. The display configuration dialog in 4.8 supports
RandR 1.2, detecting screens automatically and allowing users to pick their preferred
display resolution,
refresh rate, and
display rotation. Multiple displays can be configured to either work in
clone mode, or be placed next to each other. Keyboard selection was revamped to be easier and more user-friendly. Also, the manual settings editor was updated to be more functional. The 4.8 development cycle was the first to use the new release strategy formed after the "Xfce Release and Development Model" developed at the
Ubuntu Desktop Summit in May 2009. A new web application was employed to make release management easier, and a dedicated
Transifex server was set up for Xfce translators. The project's server and mirroring infrastructure was also upgraded, partly to cope with anticipated demand following the release announcement for 4.8. Xfce 4.10, released 28 April 2012, introduced a vertical display mode for the panel and moved much of the documentation to an online
wiki. The main focus of this release was on improving the user experience.
Modern Xfce Xfce 4.12 was released on 28 February 2015, two years and ten months later, contrary to mass Internet speculation about the project being "dead". The target of 4.12 was to improve user experience and take advantage of technologies introduced in the interim. New window manager features include an
Alt+Tab dialog, and smart multi-monitor handling. Also, a new power management plugin for the panel's
notification area was introduced, as well as a re-written
text editor and an enhanced
file manager. Xfce 4.12 also started the transition to
GTK 3 by porting application and supporting plugins and bookmarks. With 4.12, the project reiterated its commitment to
Unix-like platforms other than Linux by featuring
OpenBSD screenshots. Xfce 4.13 is the development release during the transition of porting components to be fully GTK3-compatible, including xfce-panel and xfce-settings. The planned release of Xfce 4.14 was announced in April 2016 and was officially released on 12 August 2019. The main goals of the release included porting the remaining core components from GTK 2 to GTK 3; replacing the dependency on with
GDBus, GNOME's implementation of the D-Bus specification; and removing deprecated widgets. Major features were postponed for a later 4.16 release. The minimum GTK 3 version was bumped from 3.14 to 3.22. Xfce 4.16 was released on 22 December 2020. Some notable changes in this release include new icons with a more consistent color palette; improved interfaces for changing system settings; various panel improvements like animations for hiding, a new notification plugin with support for both legacy SysTray and modern StatusNotifier items, and better support for dark themes; and more information included in the About dialog. Xfce 4.18 was released on 15 December 2022. This release mainly focused on new features and improvements to the Thunar file manager including an image preview sidebar, split view, recursive file searching, better mime type handling, per-file color highlighting, undoing up to 10 actions, a recently opened files location, restoring open tabs on startup, and a customizable toolbar. Other changes include a keyboard shortcut editor and merging the date and time plugins. Xfce 4.20 was released on 15 December 2024. This release mainly focused on restructuring preparing Xfce components for
Wayland support. As of this release, almost all Xfce components support Wayland and can be used on Wayland via a compatible compositor such as labwc or Wayfire, as Xfwm 4.20 and Xfdashboard 4.20 do not have complete Wayland support yet. As such, the Wayland session of Xfce 4.20 is considered experimental and only recommended for advanced users. == Software components ==
