If running into any issues specific to the environment which is not already fixed in existing releases, contact Fortinet TAC Support to investigate the issue. Special builds are meant to be deployed for a limited time frame and customers are advised to move to the next maintenance build with their fixes as soon as it is available. Engineering special builds are fully supported by the Fortinet Advanced Support team and, in some specific instances, by Fortinet TAC Support.

AC and DC models use the same firmware image.
FAQ:
What does it need to take into consideration when deciding on the release to use?
Review the latest release notes to check if any known issues could impact the deployment.
What is taken into consideration for a Recommended Release?
Typically Recommended Releases are also labeled as 'Mature' releases.
Significant field deployment of 40,000 or more FortiGates that have installed the recommended build.
No high-severity vulnerabilities that are without mitigating steps or workarounds.
How often is the Recommended Release KB reviewed?

Why do some platforms differ in releases?
New platforms may be on initial New Product Introduction release and will have GA builds in a staggered process after FortiOS GA has been released.
Older products may not support the latest recommended FortiOS release and hence the recommended release will be the latest FortiOS the device can support.
