Version 7.2.3 sits in the “mature” zone of FortiOS. It is not the bleeding edge (7.4/7.6), but it is far more stable than the early 7.2.x releases. Build 1262 specifically fixed several annoying SSL VPN memory leaks and IPS engine crashes present in earlier 7.2 builds.

If you are running a homelab or a small production edge: 7.2.3 is a sweet spot. It supports Let’s Encrypt automation, ZTNA tags, and the new SSL VPN portal UI without the bugs of 7.0 or the feature churn of 7.4.
