Upgrade path
A feature that was introduced in FortiSandbox v4.2.0 causes a critical bug that only affects FSA-1000F, FSA-500F and VM after upgrading to v4.2.1. We strongly recommend that customers who have upgraded to v4.2.1 upgrade to v4.2.2. Customers upgrading from v4.2.0 should upgrade to 4.2.2.
