"GNOME 2.20 is the latest version of the GNOME Desktop: a popular, multi-platform desktop environment. GNOME's focus is ease of use, stability, and first class internationalization and accessibility support. Based on Free and Open Source Software, GNOME provides all of the common tools computer users expect of a modern computing environment, as well as a flexible and powerful platform for software developers."
The improvements in GNOME 2.20 include: Improved support for right-to-left languages; desktop search integrated into the file chooser dialog; convenient new features in the Evolution email and calendar client; enhanced browsing of image collections; simplified system preferences; efficient power management and incredibly accurate laptop battery monitoring. Developers receive more help with application development thanks to a new version of the GTK+ toolkit, improved tools, and a great new documentation web site.
