Product Sunset Policy

Acrolinx sunsets development and technical support on older products so we can focus our resources and ensure our current products and services are optimal.

Technical Support

Acrolinx provides technical support for the latest versions and the versions immediately preceding them. Learn more about our support policy in the Knowledge Base.


One exception to the sunset policy is when customers with a discontinued version upgrade to a current version. To assist these customers, support for the older version is available.

When a version is sunsetted or retired, Acrolinx will inform you via the customer newsletter.

Since we regularly update this sunset policy page, come back to visit it often to note any new information.

Core Platform

Core Platform updates are distributed as Acrolinx Private Cloud, Standard Stack, or Classic. Here's a full list of Acrolinx Core Platform Releases.

Standard Stack and Classic updates are supported for 18 months after release date, excluding maintenance releases.

"Classic" is our new term for "On-Premise".

Currently, we support the following Standard Stack and Classic versions:

If you're using an older version of the Core Platform, please contact our support team to upgrade.


Support for integrations isn’t an exact science. If we offer an update path to a newer Acrolinx Integration for your editor, we require you to update to that version. Check the Compatibility Guide to see if we support your editor version. Since we've introduced the Sidebar Integrations, we've stopped adding new features to the Classic Integrations.
