Gnome 2.20 has been released and the (expansive! easy to read!) release notes say it includes:
"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."
