Cisco IOS Release 15.2(4)JA has these new features:

Cisco IOS Release 15.2(4)JA supports IPv6 protocols. IPv6 is the replacement internet protocol for IPv4. 
It uses 128 bit addresses as opposed to 32 bit addresses that are used in IPv4. Cisco IOS Release 
15.2(4)JA supports these unicast addresses:

Aggregatable Global Address: These addresses are globally routable and reachable on the IPv6 
portion of the Internet. Global addresses are identified by the Format Prefix of 001.

Link-Local Address: These addresses are automatically configured on interface using:

  link-local prefix FE80::/10 (1111 1110 10) 

  interface identifier in the modified EUI-64 format

Cisco IOS Release 15.2(4)JA supports guest access to the network. Guest networks provide access to the 
Internet and intranet without compromising the security of the host enterprise network.

Cisco IOS Release 15.2(4)JA provides support for 802.11w protocol. Unlike encrypted data traffic, the 
management frames are sent in an unsecure manner while using the 802.11 protocol for data transfer. 
The standard 802.11w protocol ensures that the data transfer is secured by applying robust management 
frame protection protocols.
