Cairo Dock （原名 Gnome dock) 是一个适用于 Linux 桌面的 Dock 类程序。Cairo Dock 2.0 添加了诸多新特性，包括完全支持 OpenGL、提供新的动画及视觉效果的插件、新的 applet、重写了配置面板、新增了很多主题等等。

Cairo Dock 3.2 的变化：

• improved multi-screen support: you can now choose the screen for each dock (or all screens), support for desktop names, more;
• new applets: Screenshot and Indicator-Generic (a plugin to display all the available Ubuntu indicators into the dock; you can define a blacklist if you don’t want some indicators to show up);
• new Sound Effects plugin which adds sounds to some actions on the icons;
• better GNOME Shell support (for instance, all windows with the same class are displayed);
• GDM user switching support;
• the note taking applet can now work without Tomboy or Gnote;
• Systemd support (Arch Linux, Fedora, etc.) for session management;
• icons and overlays should be less blurry;
• improved most plugins/applets: Application Menu, Clock, Gvfs integration (you can now mount encrypted volumes that require a password, various fixes), Keyboard Indicator, etc.;
• more!
