Release Notes

Please review the Release Notes for changes in this release:
https://docs.securityonion.net/en/2.4/release-notes.html

Known Issues

Here are some known issues that should be resolved in later releases:

• You cannot do an in-place upgrade from 2.3 to 2.4. We are still investigating data migration.
• Upgrades from this 2.4 Beta release to anything else will not be supported. Starting in RC2 we will support soup to upgrade 2.4 grids.
• Ubuntu 20.04 support is not available until RC1. This has to do with a 3rd party dependency. 
• ATT&CK Navigator doesn’t work correctly yet.
• so-import-evtx imports logs but they don't get parsed correctly.
• The following installation modes are NOT supported at this time:
• Heavy Node
• Receiver Node
• Analyst Workstation

Transition from 2.3 to 2.4

When we release the final version of Security Onion 2.4, we will announce an End Of Life (EOL) date for Security Onion 2.3. Security Onion 2.3 will continue to receive security patches and priority bug fixes until it reaches EOL.
