Is Pan OS 3.1.4 stable?

Not applicable

I currently have PanOS 3.1.2. All my devices are currently in tap mode. It was recommended to upgrade to Pan OS 3.1.4 due to a bug in the 3.1.2. Does any one know what the bug is and also would like to know if 3.1.4 stable?

Of course there are known issues in 3.1.4 too, check that document.  Some of these probably impact you.

Addressed Issues in 3.1.4.


The following issues have been addressed in this release:

• [21052] Occasionally user to IP mapping is corrupted and users are unnecessarily
presented with a captive portal login page.
