The GNOME Desktop is released every six months with many new features, improvements, "bug" fixes and translations, and GNOME 2.20 continues this tradition. To learn more about GNOME and the qualities that distinguish it from other computer desktop environments (like usability, accessibility, internationalization and freedom) visit the About GNOME page on our website.

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.

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.

2. What's New For Users

The GNOME Project's focus on users and usability continues in GNOME 2.20 with its hundreds of bug fixes and user-requested improvements. The sheer number of enhancements make it impossible to list every change and improvement made but we hope to highlight some of the more exciting user-oriented features in this release of GNOME.

2.1. Email and Calendar GNOME's email and groupware client, Evolution, has several new features. The new attachment warning could mean the end of those "Sorry, I forgot to attach the file" emails. If you try to send an email that contains the word "attachment" (or similar words), but don't actually attach a file, you will see a helpful warning. Figure 1 Evolution's attachment warning. Evolution now shows an icon in your panel's notification area when you have new email. Note that, because this is currently only a plugin which is not yet fully integrated into the main preferences, you need to disable the plugin itself if you would like to disable this feature. Figure 2 Evolution's new notification icon. Moving your configuration and Email archive to a new computer is now much easier thanks to the new Backup/Restore feature. Figure 3 Evolution's backup feature. The new "Magic Space Bar" support is hard to find, but useful - it means you need just one key to read new mails in all your folders. Just press the space bar to scroll the message preview window to the end of the email, then press it again to view the next unread email in that folder. When you've read all the emails in that folder, press it again to show the first unread email in the next folder. Evolution's calendar feature also has some useful improvements. The search interface allows advanced searches such as those already available for email and address book searches, and you can save your searches to run them again later. The Show drop-down now provides quick access to the next 7 day's appointments and to active appointments. Figure 4 Evolution's 7 day events view. In addition, the Email client now moves threads to the top of the list when a thread has a new Email, when using the threaded view.

uses the standard GTK+ printing system, using the same dialog windows as other applications, while providing more printing options than before.

allows you to choose the Spam plugin (SpamAssassin or BogoFilter) via its preferences. And SpamAssassin will now actually learn when you mark emails as Junk or Not Junk. Users of Microsoft Exchange will welcome improvements to Evolution's Exchange support, which include: Access to Exchange's delegation feature so that a colleague can handle your work while you are away.

Faster use when offline.

Faster loading of folders.

2.2. Web Browser GNOME's integrated web browser, Epiphany, has been subtly but significantly improved. For instance, inline completion in the address bar is now more intuitive. When you use the cursor keys to select from the drop-down list, the current selection is shown immediately in the entry box, so it's easier to see what address will be used when you press enter. This drop-down menu lists addresses from both your history and bookmarks, and it now shows the web site icons (favicons) for history items, as it already did for bookmark items. Figure 5 The web browser, showing bookmarks and history in the address bar, with favicons. By popular request, there's a new "smooth scrolling" preference that makes it easier to see where to continue reading when scrolling large web pages. It is not enabled by default because several users have reported that it can cause eye strain.

2.3. Image Viewing GNOME's image viewer, eog, is now faster and more stable. The new image properties dialog provides easy access to basic information and metadata for your images, and now includes XMP (Extensible Metadata Platform) data that your camera or software might store in your image files, along with the existing EXIF data. This might include location, copyright information, license, and tags. And you can now easily open an image in another application, such as the GIMP, by using the new "Open with..." menu item. When you've made your changes and saved the file then your picture will be updated in the image viewer automatically. This is also available in the new right-click menu in the image collection pane, at the bottom of the window, along with other useful actions. That image collection now has large vertical buttons at the left and right, making it easier to browse through your pictures. Figure 6 The Image Viewer, with the properties dialog and the Open With menu.

2.4. Document Viewer GNOME's Evince viewer, for PDF and Postscript files now supports interactive PDF forms, allowing you to enter information into a PDF that you receive, to save or print. Page rendering in the new version is now noticeably faster. Figure 7 The Document Viewer, editing a form. You can also now save images from PDF documents and print documents with multiple PDF pages per sheet.

2.5. Sound and Video Not all distributions like to install all multimedia codecs by default, due to the need to obtain patent licenses for some codecs in some countries. This means that applications can not always read every file format by default. But applications such as GNOME's video player, Totem, can now offer these new codecs to the user for installation. This is actually implemented by your distribution, which may make its own decisions about how to obtain the codecs. Here's how it looks in Ubuntu: Figure 8 The video player offering download of a codec. Totem's support for embedded videos in web pages has also improved, supporting more web pages, showing a pulsing play button when you need to press play to start the video, and now allowing you to go into full-screen mode from the web page.

2.6. Note-Taking Tomboy, the GNOME note taking application, has also added some significant new features, the first of which is note synchronization. Tomboy can now use WebDAV or ssh to connect to a remote server and synchronize all the notes that a user has made. This allows for users who use multiple computers to keep one set of synchronized notes between all the machines. Simple conflict resolution between the server and the Tomboy clients ensures that there is no data loss in case of a note conflict. Figure 9 Tomboy with notes synchronized between two computers. Furthermore, Tomboy now remembers your open notes, showing them again when you restart the application.

2.7. Text Editing GNOME's simple but powerful text editor, gedit, has an all-new syntax-highlighting system which now supports syntax highlighting for scripting languages such as PHP and Ruby even when embedded in HTML, as well as highlighting of text such as "TODO" or "FIXME" inside code comments, and highlighting of gtk-doc source code documentation. You can even choose from several color schemes in case you are already familiar with the colors used by a different text editor. Figure 10 The text editor's color schemes.

2.8. File Management The file chooser dialog now shows the recent files list and can use desktop search systems such as Beagle or Tracker, making it easier to find your files when you need them, without interruption. Figure 11 Performing a search in the file chooser dialog. The Nautilus file manager now shows more information in the "Properties" window for drives, including a pie graph that easily shows how much space is left. In addition, you can now see the overall disk usage in the Disk Usage Analyzer utility. Figure 12 The properties dialog for a hard drive. (Observant users will notice the bug with the type, size, and mime type information in that screenshot. We hope to have that fixed for GNOME 2.22.) The file manager also now uses the EXIF camera information in some image files to rotate its thumbnails when appropriate. This means that, when you take a picture with your camera and import it into GNOME, the orientation of the thumbnail will be correct, whether it was taken as landscape or portrait. Figure 13 The file manager showing correctly orientated image thumbnails. The file-roller archive manager can now open and save archives from networked locations, such as mounted ssh:// servers, by using the same gnome-vfs system that is already used by other GNOME applications. It is also now possible to copy/paste and drag-and-drop files between archives.

2.9. Panel The GNOME Panel can be seen at the top and bottom of your screen in most distributions. It has some small but helpful improvements in GNOME 2.20. For instance, the Window List applet no longer resizes its buttons whenever the length of window titles change. This avoids annoying resizes when changing tabs in your web browser. And the Window Selector applet now sorts its drop-down list by workspace. Users of "floating panels" (which don't expand to fill the whole screen width) might notice that these panels now remain in the correct position and alignment when changing screen resolution. More work to improve the repositioning of panel applets when changing screen resolution is planned for GNOME 2.22.

2.10. Control Panel For GNOME 2.20, the control panels have been reorganized slightly to reduce the number of control panels, making it easier to find what you need. For instance, this release marks the debut of the new Appearance control panel applet. The Theme, Background, Fonts, and Interface applets have been merged to create this new applet, simplifying the Preferences menu. Figure 14 The Appearance control panel. In addition, some of the Accessibility preferences have been moved to a new tab in the Preferred Applications control panel. Figure 15 The Accessibility tab in the Preferred Applications control panel. Wireless users may also welcome the new support for WPA encryption in the Network control panel.

2.11. Password Management The GNOME Keyring system remembers your passwords for networked servers and web sites. In GNOME 2.20, the keyring is unlocked automatically when you login and when you unlock your screen, avoiding the need for an extra password prompt. Note, however, that this feature requires some work by your distribution. You can now also change your keyring's master password via the Encryption Preferences control panel, in the GNOME Keyring tab. Figure 16 The Keyring tab in the Encryption Preferences control panel. The Password and Encryption Keys utility now shows more notification details when you import keys, and allows you to choose the archive type when encrypting multiple files. Figure 17 Encrypting multiple files.

2.12. Help System This release has seen some large changes in the infrastructure of the GNOME help browser (yelp), improving the style and layout. In addition, the colors now better match your current theme. Help pages also now appear more quickly, as individual pages are now loaded on demand instead of the entire manual being parsed unnecessarily. Figure 18 The help browser.

2.13. Power Management GNOME's Power Manager now saves profile information about your batteries over time, to provide a far more accurate estimation of the time remaining, even with old worn-out batteries. It even knows about many battery models that have been recalled by their manufacturers. Figure 19 The power manager warning about a worn-out battery. Several parts of GNOME, such as the volume mixer have also been corrected to remove unnecessary polling, resulting in power savings.

2.14. Login and Screensaver Users could already choose their preferred language when logging in to GNOME, but now they can even see the login screen in their own language as soon as they choose it, thanks to an improved GDM (Gnome Display Manager). The GNOME Screensaver now allows people to leave you a note while your screen is locked, by clicking the "Leave Message" button. You'll see these messages when you login. Figure 20 Notes left for you while your screensaver was active.

2.15. Right-To-Left Languages Languages such as Arabic and Hebrew are written from right to left. Users of these languages expect most user interface elements to be similarly mirrored, compared to left-to-right user interfaces. GNOME 2.20 improves the support in the following ways when using these languages: Window title buttons (such as minimize, maximize, and close) appear in mirrored order.

Window title menu items are now aligned to the right.

The alt-tab window switcher lists and moves through windows from right to left.

The ctrl-alt-arrow workspace switcher lists and moves through workspaces from right to left, Figure 21 Switching windows when using Arabic. Notice the reversed buttons in the window title bars.
