Best reliable and stable FGT firmware version

[Hemin88]

Hi, I just want to know this in generic, 
I know it depends on environment of each network 

But is there a top recommended FGT firmware version that would be stable.
in My environment we are upgrading to 7.0.16

Hi Hemin88,

Always use a mature version, the following article explain the differences between mature and feature.

Version 7.0.x, 6.4.x, 6.2.x are out of engineering support, avoid those version if possible.

Hi @Hemin88 ,

Without your FGT hardware model info, we can't provide appropriate recommendations. 

For example,  let's say, 7.0.16 is a stable firmware.  But your FGT model is 30E. There is no 7.0 image for FGT 30E at all.  Is FortiOS 7.0.16 a suitable recommendation for you in this case?
