Ubuntu Common Release Notes

The main Ubuntu Release Notes covers both many of the other packages we carry and more issues common to every Ubuntu flavor.

Major Updates

  • Xfce 4.16 features many improvements over the previous release, including:
    • A new “StatusTray” panel plugin, consolidating the StatusNotifier and System plugins into a single powerful and consistent plugin.
    • Dark mode for the Xfce panel to use a dark appearance without otherwise light themes.
    • Support for fractional scaling in the Display preferences.
    • Queued file transfers, paused copy/move operations, per-directory view settings, and more added to the Thunar file manager.
    • For more information about Xfce 4.16, check out the release announcement, changelog, and tour.
  • Hexchat and Synaptic are now included in Xubuntu 21.04.
    • HexChat is an highly-configurable open source IRC client and is recommended over Pidgin for IRC communication. In Xubuntu, it's preconfigured to connect to the #xubuntu channel on Freenode.
    • Synaptic is an advanced package manager for apt. It joins GNOME Software on Xubuntu and can be safely used alongside it.
  • Ayatana Indicators are now used with LightDM GTK+ Greeter and the Xfce Indicator plugin. This change may affect your indicator usage, as not all existing Application Indicators have been ported.
  • The full Adwaita icon theme is now included. Previously, we shipped a partial version of this icon theme as required by GTK 3. Using the partial version was a sub-par experience, so we've brought in the full version!
  • Xubuntu 21.04 now includes a “Minimal” install option on the main ISO. This installation option is similar to the Xubuntu Core installation image, and strips Xubuntu down to a might lighter base. To see the packages that are removed with the minimal install, check out our seed file.

UX Updates

Keyboard Shortcuts

Our keyboard shortcuts were updated to better align with Xfce 4.16 and other popular desktop environments. For a full list of keyboard shortcuts, click here.

Desktop

  • The File System and removable device icons are no longer displayed on the desktop
  • The applications menu has been removed from the desktop right-click menu
  • The Texinfo launcher has been removed from the menu
  • The PulseAudio Volume Control launcher has been removed from the menu and replaced with a “Sound” option in the Settings Manager

Panel

  • The StatusNotifier and Systray plugins have been merged and replaced with the StatusTray plugin
  • The separator between the clock and tray icons was replaced with padding on both sides, removing the unclickable space between the plugins and giving the clock some breathing room
  • The PulseAudio plugin is now configured with window focus support, improving integration with third-party music players

Thunar

  • The path bar is now used by default, making it easier to navigate up paths
  • Folders can now be opened in a new tab by middle-clicking them
  • Special folders (such as Home) will no longer change the window icon, adding consistency to the panel
