# When will Niagara AX (4.4) go off support?

## Niagara 4.4 will go off support October 1, 2021, which means there will be no future updates, patches or cyber security fixes for this version.

**After October 1, 2021, there will be no further update builds, changes or security updates to Niagara 4.4. **Also, Niagara 4.4 will not be available for download. If you have customers that haven’t refreshed their Niagara Framework® software for years, we hope that you will generally encourage them to deploy the current release, Niagara 4.9. They’ll be pleased at how much more productive and cyber-secure they will be.
