o Minor features:
- AutomapHostsOnResolve now support IPv6 addresses. By default, we
prefer to hand out virtual IPv6 addresses, since there are more of
them and we can't run out. To override this behavior and make
IPv4 addresses preferred, set NoPreferIPv6Automap on whatever
SOCKSPort or DNSPort you're using for resolving. Implements
ticket #7571.
- AutomapHostsOnResolve responses are now randomized, to avoid
annoying situations where Tor is restarted and applications
connect to the wrong addresses.
- We never try more than 1000 times to pick a virtual address
when AutomapHostsOnResolve is set. That's good enough so long
as we aren't close to handing out our entire virtual address
space; if you're getting there, it's best to switch to IPv6
virtual addresses anyway.
