Notas de Lançamento do GNOME 2.12

1 Novidades para Usuários

1.1 Desktop

1.1.1 Look and Feel

GNOME 2.12 introduces a new standard theme, also known as "ClearLooks", making your desktop more attractive while remaining simple and uncluttered.

Figura 1 ‒ Attractive, friendly, simple: the new default theme.

1.1.2 The File Manager

The file manager, also known as Nautilus, has several user interface improvements in GNOME 2.12. Most noticeably, the list view can now show files in directories, allowing you to navigate down to a sub-folder and open a new folder window only when necessary. Also for your convenience, the Bookmarks menu now shows the same locations as the File Chooser dialog.

In GNOME 2.12, dragging text from an application to a folder window will save you time by creating a new text document. You'll also notice that GNOME now shows a preview of the text being dragged, instead of just an icon.

Figura 2 ‒ clean-cut and powerful: the Nautilus file manager

There are also major improvements to the browse mode, making it similar to GNOME's existing File Chooser dialog:

  • Places and Bookmarks may be displayed in a sidepane.
  • The location is now shown with the GNOME's path bar instead of a text entry. The text path is still available via the Control-L keyboard shortcut.

GNOME's simple CD-burning feature can now copy Audio CDs as well as data CDs. Just right-click on the CD after inserting it.

1.1.3 Clipboard

GNOME now remembers data that you copy, even when you close the window from which it was copied. This long-standing problem has finally been solved without the performance problems usually associated with clipboard daemons, by allowing applications to explicitly request the use of this feature.

1.1.4 The Panel

The panel, which you normally see at the top and bottom of the screen, allows you to start applications and control various aspects of your environment. In GNOME 2.12 vertical panels with menus are possible, thanks to the rotated menus.

You might also notice that applications may now flash their names in the Window List, to indicate that they are ready. For instance, an instant messenger application could flash its icon when a friend sends a message.

1.2 Aplicações

1.2.1 Reprodutor de Filmes

GNOME's "Totem" video player, uses GNOME's GStreamer multimedia framework. In GNOME 2.12, the video player now has a playlist sidebar instead of a separate window, and supports DVD menus and subtitles.

1.2.2 CD Ripping

GNOME's CD ripper easily extracts audio from CDs for later playback on your PC or portable music player. And now, you can play tracks before extracting them. This latest version can also extract files to networked servers or removable devices, using GNOME's VFS system.

Figura 5 ‒ O extrator de áudio

1.2.3 Navegador Web

GNOME's "Epiphany" web browser is based on Mozilla yet integrates fully with the GNOME desktop environment. Improvements in 2.12 include

  • A Find Bar, as seen in Firefox, and previously available as an Epiphany extension. This allows you to find text on the page, without hiding the page behind a dialog window.
  • Mensagens de erro mais claras, mostradas diretamente no navegador.
  • Use of the standard GNOME printing system.
  • Bookmarks can be easily shared over the network.

1.2.4 Evolution

GNOME's integrated Email and Groupware client, Evolution, supports traditional mail setups as well as Novell Groupwise and Microsoft Exchange. With Evolution you can read, write, and manage your emails, contacts, and calendar events.

In GNOME 2.12 evolution now has an easier-to-use menu layout and an improved attachments bar, and allows inline PGP encryption and PGP signatures. In addition, the calendar now allows delegation of your meeting attendance.

Groupwise proxy and IMAP accounts are now supported, and some compatibility problems were solved for people also using Mozilla Thunderbird with IMAP.

1.3 Control Center

1.3.1 About Me

GNOME now has a new About Me control panel in which you can enter your personal details, such as your telephone numbers, address, email address, and instant-messenger IDs, instead of repeating the information in several applications. You can also change your password here.

Figura 8 ‒ About Me

1.3.2 Mouse Preferences

The Mouse Preferences control panel now allows you to change your cursor theme.

Figura 9 ‒ Mouse Preferences

1.4 Utilities

The GNOME utilities have some improvements, such as:

1.4.1 Document Viewer

GNOME 2.12 has a new document viewer, also known as "Evince;" to replace the previously separate PDF and .ps document viewers. This new viewer is simpler and more convenient, with a useful search feature and the ability to show several pages at once.

Figura 10 ‒ Document Viewer

1.4.2 Image Viewer

The GNOME image viewer can now show pictures with color correction, using ICC profiles.

Figura 11 ‒ Image Viewer

1.4.3 Help Viewer

GNOME's Help Viewer, Yelp, now uses the same engine as Epiphany, the web browser. The look, feel, speed and stability of Yelp have been vastly improved.

Yelp also has improved support for locale specific formatting, allowing documentation to be rendered using language specific formatting rules, an excellent complement to the new documentation translation system, that allows translators to translate help documents as easily as applications.

Figura 12 ‒ Help Viewer

1.4.4 Search

The GNOME search tool now shows image thumbnails instead of just generic icons.

Figura 13 ‒ Search

1.4.5 Dicionário

The GNOME Dictionary now has a simplified user interface and presents the entries in an easier-to-read layout. You may now select the fonts used to show entries.

Figura 14 ‒ Dicionário

1.5 Games

GNOME's games put extra fun in the desktop. The Mines game has some improvements in GNOME 2.12 - for instance, the first click is guaranteed to clear a useful number of squares so you don't have to blindly click and hope you don't hit a mine, and an explosion graphic is drawn when you set off a mine.

Figura 15 ‒ Mines

2 Novidades para Administradores

O GNOME 2.12 tem novos recursos para facilitar a vida dos administradores de sistemas, incluindo usuários que gerenciam seus próprios computadores.

2.1 Improvements for Sabayon

As part of the work to support the Sabayon user profile manager, GNOME startup reads and touches fewer settings. Besides small performance gains, this means that GNOME 2.12 is easier to administer than ever, particularly in combination with Sabayon, which while not officially part of GNOME, makes setting up user profiles for GNOME very easy.

2.2 Editor do Menu

O menu Aplicações do GNOME agora usa a especificação de menu da freedesktop, então aplicações podem ser facilmente instaladas independentemente do ambiente desktop utilizado. O GNOME 2.12 tem uma ferramenta simples para edição do menu e, devido à padronização da infraestrutura, outras ferramentas estão sendo disponibilizadas por terceiros.

Figura 16 ‒ O Editor do Menu

2.3 Ferramentas de Sistema

As ferramentas de sistema permitem que você configure o relógio do seu sistema e a sua conexão de rede, além de gerenciar os usuários e grupos no seu sistema. No momento, essas ferramentas são apropriadas para computadores individuais, não grandes redes de computadores.

O GNOME 2.12 traz uma nova ferramenta de Administração de Serviços, que permite que você escolha que serviços serão iniciados junto com o computador.

Figura 17 ‒ A ferramenta de Administração de Serviços

2.4 Visualizador de Logs

O visualizador de logs do GNOME facilita a investigação, mostrando todos os logs em uma janela com abas e permitindo que você navegue pelos seus logs em um calendário. A nova versão do navegador também ajuda na visualização de logs arquivados.

Figura 18 ‒ O Visualizador de Logs

3 Novidades para Desenvolvedores

The GNOME 2.12 Development Platform provides a stable base for third-party software developers, and for the GNOME Desktop itself. GNOME 2.12 adds some user-visible and API improvements, while maintaining backwards compatibilty and API-stability. It also makes it easier to develop applications that run on Unix and Windows, and use important standards to interoperate with other desktops.

3.1 GTK+ Improvements

In GNOME 2.12, GTK+ 2.8 provides some interesting user-visible features, such as

  • GTK+ now uses the freedesktop Cairo drawing API, making custom widget drawing easier to implement and allowing new effects. In the near future, this should allow GNOME to use new graphics effects and take advantage of hardware acceleration, as well as improving our printing APIs.
  • Drag and drop handling has been improved and now previews blocks of text when you drag them.

In addition to these changes, which all GTK-based applications can use without recompilation, several new APIs have been added to make developement even easier. These include:

  • GtkFileChooser can now display a file-overwrite confirmation dialog when in save mode.
  • GtkWindow can have an urgency hint, instructing the window manager to, for instance, flash the window title.
  • GtkIconView now implements the GtkLayout interface, and can render items via GtkCellRendererCells.
  • GtkTextView now allows you to set a background color for pargraphs, and you can now skip over invisible text when iterating.
  • GtkScrolledWindow has functions to get the scrollbars.
  • GtkMenu now supports vertical (rotated) menus, and it can ignore keyboard focus, for special applications such as the onscreen keyboard.
  • GtkEntryCompletion's popup menu may now be wider than the Entry, and the popup can be avoided when there is only a single match.
  • GtkAboutDialog's license text can now be wrapped.
  • GtkToolButton can now use named icons from icon themes, and these iscons may also be used when dragging.
  • GtkSizeGroup can ignore hidden widgets.

See also the full list of the new API in GTK+ 2.8.

3.2 Cross-platform

The GTK+ library is already popular among developers who need to support multiple platforms, including Microsoft Windows as well as Linux and UNIX. For instance, artists may edit their images using GIMP and Inkscape on either Linux or Windows.

And now many more GNOME libraries, including ORBit2, libbonobo, libgnome, libbonoboui, libgnomeui and gnome-vfs, can build on Microsoft Windows, making it easier to build and distribute GNOME applications on that platform. While this support is not yet complete, it may be sufficient for some applications, and is expected to be complete in the next release of GTK+ and GNOME.

3.3 Standards Compliance

GNOME works closely with groups such as Standards support is a big plus for GNOME developers and users. Interoperability support improves the user experience by allowing GNOME, KDE, and other applications to work together more easily, and following open specifications helps ensure that user data is not trapped in proprietary formats.

GNOME developers are working hard with other members of the free software community through on the development of standards to allow interoperability. Those standards include: shared MIME database, icon themes, recent files, menus, desktop entries, thumbnail management, and the system tray specifications. In addition, GNOME supports CORBA, XML, Xdnd, EWMH, XEMBED, XSETTINGS, and XSMP.

4 Internacionalização

Many other languages are partially supported, with more than half of their strings translated.

5 Instalando o GNOME 2.12

Para o GNOME 2.12, nós temos um LiveCD disponível em O LiveCD permite que você experimente um desktop GNOME completo no Linux sem instalar nada no seu disco rígido. Este é o melhor jeito de ver por si mesmo o que há de novo.

For actual use, we recommend that you install official packages, such as those for your Linux distribution. Vendors are likely to package GNOME 2.12 relatively quickly, and to release new versions soon that include GNOME 2.12.

Se você for corajoso e paciente, e quiser construir o GNOME a partir do código-fonte para testar as versões mais novas e fornecer informações e melhorias, nós recomendamos uma ferramenta de construção como o GARNOME, para construir a partir de tarballs lançadas, e o jhbuild, para construir a partir do CVS.

6 Problemas Conhecidos

Todo software, quando lançado, contem falhas que os desenvolvedores conhecem, mas escolheram não consertar antes do lançamento, por vários motivos. Software livre não é diferente de software proprietário nesse quesito, exceto pelo fato de que, no software livre, nós avisamos nossos usuários sobre esses problemas.

Nós também incentivamos nossos usuários a reportar bugs para que eles possam ser corrigidos. A melhor maneira de fazer isso no GNOME é usando o Guia Simples de Bugs. Ele conduzirá você pelos passos necessários para enviar um relatório de qualidade, e garantir que ele está categorizado apropriadamente. Se você é avançado demais para qualquer coisa com a palavra "simples", também há o formulário tradicional de bugs. Mais detalhes sobre bugs já reportados podem ser encontrados no nosso Bugzilla. Entre os bugs mais visíveis do GNOME 2.12:

6.1 Lista de problemas conhecidos

  • The 'open terminal' action has been removed from the Nautilus right-click menu, in order to improve manageability and default usability. If you miss it, we recommend installing the Nautilus open-terminal plugin, which not only restores 'open terminal' to the nautilus menu, but actually makes it better by opening the terminal in the directory in which you are browsing.

7 Looking to GNOME 2.14 and Beyond

GNOME operates on a time-based release schedule, an attempt to continuously provide the best of our developers' efforts to users as quickly as we can. The following features are on the radar of GNOME developers and may land in the next few releases.

  • Support of the Apple Bonjour standard for detection of services on the network, potentially via Avahi.
  • Support of the caldav open calendar services standard in Evolution.
  • Use of Network Manager to give all network-aware apps intelligent behavior in the face of network connection and disconnection.
  • Consolidation of gtk and gnome libraries to ease development and deployment of GNOME applications, via Project Ridley.
  • Increased usage of new rendering infrastructure to improve looks and usability, for example, by integrating it with Clearlooks, our new default theme.
  • For further information, see the GNOME roadmap on our wiki.
