Ubuntu Cinnamon 22.04 LTS “Jammy Jellyfish” Beta Released + Release Notes

Hello all,

It is that time of the release cycle again! Our second ever LTS release is now officially in its Beta Stage, almost free of all critical bugs and installation blockers.

There are a LOT of new changes from our 21.10 release, so here is a rundown of everything that has changed (aside from the hundreds of stability fixes and UI updates)

  • Cinnamon Desktop Suite (as a whole) – Major Bump from 4.8.6 to 5.2.7
    • Due to the Debian Bullseye Freeze, no new packages were to be imported into unstable. Thus, Cinnamon 5.0 did not live in the repositories for long until 5.2x came along, and 21.10 did not ship with Cinnamon 5.0.
    • This version bump has occurred before in 20.04 – the 19.10 release had Cinnamon version 4.0.10 and 20.04 introduced version 4.4.8.
    • For a full list of changes, see the Cinnamon changelog:
      • Spices rework
        • A lot of the Cinnamon spices system (applets, desklets, extensions and themes) were reworked with icon fixes and other information improvements.
        • Spices can now be automatically updated – this comes along with a Python 3 CLI in the ‘harvester’ subpackage.
      • Cinnamon memory limit
        • This can be configured in cinnamon-settings. Self-explanatory; a memory limit for the cinnamon process to make memory leaks less apparent.
      • (The start of many) Y-2038 fixes
        • We still do not officially support 32-bit, but if you manually install Ubuntu on a 32-bit system and put Cinnamon on it, there will be some Y-2038 safety in there. It is still not complete yet.
  • Nemo File Manager 5.2.4
    • Another major bump from 4.8.5 to 5.2.4
    • For a full list of changes, see the nemo changelog:
      • Content search
        • This is pretty self-explanatory; this adds support for searching for custom content in files.
      • Search helpers
        • To search for a specific file type, you can use search helpers.
        • Here is a good write-up on how it works:
      • Tons of stability fixes
        • There are still many more bugs to be patched in Nemo, and many different desktops utilize it. Please report bugs to us via social media.
  • Cinnamon Screensaver
    • Another major version bump from version 4.8.1 to 5.2.1
      • Fallback Screensaver
        • Last year, there was a security issue with caribou (the virtual keyboard library) that crashed whenever special characters were added. This would cause cinnamon-screensaver, and other cinnamon components to crash. This was patched – see
        • In the event of the screensaver crashing, a fallback screensaver will be implemented – goal is to prevent security vulnerabilities from being dire
      • UI fixes and improvements
  • Other notable Cinnamon changes
    • cinnamon-settings-daemon: Trackball support was added, and Wacom LED support was removed (as now the kernel handles it).
    • cinnamon-control-center: The network section now supports DNS6, the calibrate section was removed, the display panel now allows for 3x scaling
    • cinnamon-session: Desktop Entry Specification v1.4 is now accepted
    • cinnamon-desktop: Screen reader keybinding was added, and date/time integers are now properly parsed
  • Linux Kernel 5.15.0-23
  • Yaru theme color variants can now be selected
  • Firefox 98.0.2 – will be pre-installed as a deb, but updates will migrate it to a snap for you
  • GCC version 11.2.0
  • Ruby 3.0.2p107
  • Rust 1.58.1
  • Go 1.18
  • Snap 2.55.2

And that is all, and of course many more that if I continue, this blog post won’t ever get published. Point is: we have a lot of testing to get to, so we need your help.
