Hi Shahid

We use 7.0.6 on many prod FGT and found it stable. While 7.0.5 is not.


Good Day,

Thank you for using the Community Forum. 


As a general rule, the latest release in a given train (6.4.x, 7.0.x, etc) is the 'most stable' in that it has found and corrected issues in the previous releases. Ultimately, it is a decision customers need to determine based on what technologies they are running while considering interoperability with other Fortinet technologies as well as any known issues documented in a particular release.


a) Here is the kb article on the known issues in 7.0.2

b) Here is the kb article on the known issues in 7.0.5

 c) Here is the kb article on the known issues in 7.0.6


To build on the excellent responses you've received already, Fortinet has also recently started labeling their firmware releases as either "Feature" releases (marked "F") or "Maturity" releases (marked "M"). As major releases mature from the first few point releases, i.e. 7.0.1, .2, .3, there are bugs being fixed but at the same time new features as well. As the release becomes more mature, the later releases will be fixing bugs primarily.


Ideally, if you are concerned about stability, stick with the "M" releases (which is 6.4.10 today).


If there are features in 7.0 that you absolutely need, then ideally you have an environment within which you can test it out before rolling to production.


Hello Graham,


Thank you so much for your quick response. We have checked the detail of firmware from support portal. The F mark only with 7.0.6 and 7.2.1 and M mark with 6.4.10. Due to stability i think we should go on 6.4.10 that already you have suggested to me.
