GNOME 3 (released in April 2011) replaced the classic desktop metaphor, substituting its native user interface: GNOME Shell. This action led to some criticism from the Linux community. Some users refused to accept the new interface design of GNOME and called for continued development of GNOME 2. An Argentinian user of Arch Linux started the MATE project in order to meet this demand and announced the availability of Mate on 18 June 2011.
MATE has forked a number of applications belonging to the GNOME Core Applications, and several other applications have been written from scratch. The forked ones have been renamed, with most names in Spanish.
We consider MATE yet another desktop, just like KDE, Gnome 3, Xfce etc. ... and based on the popularity of Gnome 2 in previous releases of Linux Mint, we are dedicated to support it and to help it improve.
New features have been added to Caja such as undo/redo and diff viewing for file replacements.
MATE 1.6 removes some deprecated libraries, moving from mate-conf (a fork of GConf) to GSettings, and from mate-corba (a fork of GNOME's Bonobo) to D-Bus.
MATE is also available in the official repositories of several other Linux distributions, including Ubuntu, Arch Linux, Debian, Mageia, Gentoo, openSUSE and PCLinuxOS. Aside from that, there are third party repositories for Slackware. Version 3.5 and up of GhostBSD include MATE as the default desktop environment, making it the second inclusion of MATE as a default desktop, after Linux Mint, and the first in a BSD-derived OS.
