Notable change: In nat46 mode, snid now binds outbound connections to same source port that the client used. This avoids putting strain on the kernel's automatic port assignment, fixing an issue where unrelated outbound connections could fail with EADDRNOTAVAIL. It also makes the proxying a bit more transparent.

Full Changelog: v0.3.0...v0.4.0

When the ALPN protocol is xmpp-client or xmpp-server, snid will now do a SRV record lookup to determine the backend's IP address, to emulate the behavior of XMPP clients or servers connecting directly to the backend.

It is now possible to listen on all IPv4 interfaces by specifying an address of 0.0.0.0, e.g. -listen tcp:0.0.0.0:443
