After a feature release has matured (typically 6-12 months), Fortinet designates certain versions as "Mature." These are highly stable, thoroughly field-tested, and recommended for production environments requiring maximum uptime.
Feature releases are the earliest iterations of a new minor release branch (typically up to patch 3 or 4). These versions contain the latest engineering innovations, user interface redesigns, and newly developed security modules. They are ideal for test labs, tech-savvy early adopters, or organizations requiring a specific new feature to solve an immediate business problem. Mature Releases
FortiGate firmware is not merely low-level code; it is the entire operating system, known as , packaged specifically for Fortinet hardware or virtual machines. fortigate firmware
One of the most common mistakes in firewall administration is upgrading directly from an old firmware version to the latest release.
