Znuny LTS 6.5.20 Current LTS
Not sure which to pick? Stable gets the latest features on a regular release cadence. LTS (Long Term Support) gets extended security and bugfix maintenance on a conservative track — ideal for production systems that value predictability over new features.
Previous versions
These versions no longer receive updates. If you're still running one of them, we recommend planning a transition to 7.3 (current stable) or LTS 6.5. Older patch versions are listed in the full release archive.
