904a5734375869ffb504ed8cde6b68cafadb6d64Bob Halley @ Semantics of certain pathological address match lists, in

e4e071ae12aee942fefc2c0a3280e402938669deBob Halley particular those involving double negation, have changed.

c50fd34a4e0e6978f8ca5f6f3ad8545549c3cfeeBob Halley The new semantics are generally safer. IPv6 addresses

25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley are supported, but the predefined ACLs "localhost" and

25e43e68b7431d5e4ff8b5427108cd7f5f9bcf3eBob Halley "localnets" match IPv4 addresses only.
