Release Notes: This release fixes several bugs in IPv6 handling and reintroduces host names (reverse-resolved using the getnameinfo function) in verbose messages, which were disabled until now. The argument to -q now works as advertised. It also improves portability.
Release Notes: This release fixes a bug in which only 8k of the data to be sent to the remote host was accepted.
Release Notes: This release cleans up the code in netcat 1.10, modernizes some things (including support for IPv6), and has some popular patches, including those that Debian uses for its own netcat. It does not do reverse DNS lookups anymore, but this is only temporary. Instead, source routing has been removed because nobody leaves it enabled anymore. autoconf is now used.
