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.
