"Almost eighteen months ago, on the 18th of October 2007,
Canonical announced the release of Ubuntu 7.10, codename Gutsy
Gibbon. Many important features and updates made Ubuntu fans all
over the world extremely happy and eager to upgrade. The default
desktop environment for Ubuntu (GNOME) reached then a very
important milestone: 2.20, bringing a huge list of changes.
"Ubuntu 7.10 (Gutsy Gibbon) was the first Ubuntu operating
system to include Compiz 3D effects enabled by default. Tracker
replaced Beagle as the desktop search tool of choice. Also, the
Ubuntu restricted extras package was included, enabling users to
install almost all proprietary codecs on their system with just a
few clicks. Not only that, but the Adobe Flash Player 9 could be
installed just as easily, allowing the increasing number of
flash-based websites to display better."
