I just released Thunar-0.3.0beta1 and libexo-0.3.1.6beta1 as part of Xfce 4.4BETA1 (separate tarballs are provided for users of Xfce 4.2.x that don’t want to upgrade yet, and users of other desktop environments). As suggested by the name, it is a beta release and it is thereby considered to be more or less stable in what it does, but it is still not a final version.
You will need atleast libxfce4util 4.2.2, GTK+ 2.6.4, shared-mime-info 0.15 and desktop-file-utils 0.10 to build and run Thunar. In addition Gamin or FAM are highly recommended to enable file system monitoring in Thunar. For HAL support on Linux, the libhal-storage-devel package is required (0.5.0 or above). The
README file contains a complete list of dependencies and optional packages.
