Yes, there is one. I think it is documented in release note, but quick explanation.
in 10.2, IPV6 is disabled by default on interfaces. It was enabled in 10.1.
To keep feature consistency (IPv6 still enabled) between 10.1 and 10.2,
ipv6 address link-local is inserted in the configuration to maintain IPv6 enabled. If you don't need v6, you "simply" have to remove ipv6 address link-local from your interface configuration.
