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.

  • 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
