I am a bit confused to see AsyncOS 6.3.1-025 as the "only" listed release on the IronPort support portal. A few days ago it was still available for "FCE" and not listed for all customers. However, and this is what really confuses; I have not yet received an email stating that the above mentioned AsyncOS is now GA.
Please be so kind and bring a bit more light into this.
