documents were updated to reflect the addition of new features and changed functionality and to address 
reported documentation issues:

The documentation updated for Version 5.3.1 contains the following errors:

The documentation incorrectly states the following about devices in a stack: 

If a secondary 

device fails, the primary device continues to sense traffic, generate alerts, and send 

traffic to all secondary devices. On failed secondary devices, traffic is dropped. A 

health alert is generated indicating loss of link.

The documentation should specify that, when a secondary device fails, the system sends the primary 
device into maintenance mode. The primary device does not sense traffic, generate alerts, or send 
traffic to secondary devices. A health alert is generated to indicate loss of link. (122708, 123380, 
138433)

The documentation does not reflect that the system removes interfaces from your security zone 
configurations when you modify your ASA device security contexts and switch from single context 
mode to multiple context mode or visa versa. (141050, 141064)

Before you begin the update process for Version 5.3.1, you should familiarize yourself with the behavior 
of the system during the update process, as well as with any compatibility issues or required pre- or 
post-update configuration changes.

Cisco strongly recommends you perform the update in a maintenance window or at a time when the 
interruption will have the least impact on your deployment.
