Hi,
This new version added some sweeping changes to SOCKSv6. The following
are the most notable:
* All fields are now guaranteed to be aligned. This makes
implementation easier on platforms that can't handle unaligned memory
accesses (notably ARM).
* It is now possible to have the proxy relay back the resolved host
name, in essence mimicking the behavior of gethostbyname/getaddrinfo.
This is useful for applications that are "proxified" using LD_PRELOAD.
Such applications will not be forced to leak information via DNS
queries. (This functionality is present in Tor as a non-standard SOCKS
extension.)
* Option kinds are now 2 bytes in size. We've also flattened the
kinds/types/codes in order to save space.
* 8-byte UDP Association IDs.
On the implementation front, Sixtysocks
(https://github.com/45G/sixtysocks) is now compliant with -07 and no
longer depends on a GPL-licensed TLS library. The message library
(https://github.com/45G/libsocks6msg) is up-to-date and fully-featured.
Cheers,
Vlad

Abstract:
The SOCKS protocol is used primarily to proxy TCP connections to
arbitrary destinations via the use of a proxy server. Under the
latest version of the protocol (version 5), it takes 2 RTTs (or 3, if
authentication is used) before data can flow between the client and
the server.
This memo proposes SOCKS version 6, which reduces the number of RTTs
used, takes full advantage of TCP Fast Open, and adds support for
0-RTT authentication.
Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
