Two new versions of socat are available in the Cygwin distribution:  - current
  2.0.0-b7-2 - test

Version is a new upstream release, with several security fixes. Please
see the full changelog at http://www.dest-unreach.org/socat/doc/CHANGES. All
users of socat 1.x are urged to upgrade to the new release.

Version 2.0.0-b7-2 is identical to 2.0.0-b7-1.  I had to update the release
numbers to force a new upload with the corrected setup.hint (below).

The -1 versions of these two releases were briefly released with an incorrect
setup.hint file, that failed to identify version 2.0.0-b7 at a test release.  If
if you updated Cygwin during that time, you got automatically upgraded to the
2.0.0-b7 release.  The problem is fixed now, so if you want to go back to using
the 1.7 series, please do that manually and your choice will stay.  Sorry about

socat is a relay for bidirectional data transfer between two independent data
channels. Each of these data channels may be a file, pipe, device (serial line
etc. or a pseudo terminal), a socket (UNIX, IP4, IP6 - raw, UDP, TCP), an SSL
socket, proxy CONNECT connection, a file descriptor (stdin etc.), the GNU line
editor (readline), a program, or a combination of two of these. These modes
include generation of 'listening' sockets, named pipes, and pseudo terminals.
socat can be used, e.g., as TCP port forwarder (one-shot or daemon), as an
external socksifier, for attacking weak firewalls, as a shell interface to UNIX
sockets, IP6 relay, for redirecting TCP oriented programs to a serial line, to
logically connect serial lines on different computers, or to establish a
relatively secure environment (su and chroot) for running client or server shell
scripts with network connections.
