yahns 1.13.0 - some user-visible improvements...
And probably a billion new regressions!

yahns now allows users to skip the Rack::Head, Rack::Chunked and
Rack::ContentLength middlewares to ease migrating from/to other
real-world Rack HTTP servers.  Most notably, our chunked
encoding implementation is a bit faster than Rack::Chunked by
taking advantage of the writev(2) syscall:


There's also rack 2.x fixes in the test case and extras/ section
(these incompatibilities did not affect existing users unless
they use the wonky extras/ section).

There's also some graceful shutdown fixes, the process title is
now changed to display the number of live FDs.

Of course, there's the usual round of documentation improvements
which are systemd and OpenSSL setup-related this time around.

However, the majority of changes (proxy_*, wbuf_lite), affect
currently-unadvertised functionality which is subject to removal
or incompatible config changes.  However, they are used to serve
our mailing list archives at:
