A Free Software, multi-threaded, non-blocking network
application server designed for low _idle_ power consumption.
It is primarily optimized for applications with occasional users
which see little or no traffic. yahns currently hosts Rack/HTTP
applications, but may eventually support other application
types. Unlike some existing servers, yahns is extremely
sensitive to fatal bugs in the applications it hosts.

Changes:
yahns 1.16.0
This release fixes warnings for users combining Rack::Deflater
with HTTPS support:
https://yhbt.net/yahns-public/20180714005630.11812-1-e@80x24.org/
yahns-rackup(1) users may not specify "-O listen=inherit"
when spawning from systemd. The "listen" directive may
be omitted entirely from the yahns-config(5) files.
A few other cleanups and nothing interesting, otherwise.
20 yawn-worthy changes since v1.15.0 (2017-03-23):
config: more descriptive variable name
proxy_pass: comment explaining what rack.hijack calls
USR2 upgrades may use Process.spawn for vfork
avoid Thread#[] and Thread#[]= across threads
gemspec: declare Ruby 2.0+ dependency, here
test_bin: SO_KEEPALIVE value only needs to be true
rackup_handler: remove unnecessary branch
test_bin: use RbConfig.ruby for non-standard names
allow omitting specifying socket name when inheriting listen socket
server: fix incomplete comment about SSLContext#setup
test_rack_env: additional test for Rack environment
test: allow setting TAIL env to watch error logs
fix some unused variables
tests: thread-safety fixes
test/server_helper: describe reason for termination
test/test_ssl: set SSLContext#security_level=0
doc: https:// URLs instead of git://
http_client: clear backtrace on "wrong version number" in OpenSSL
openssl_client: do not attempt writes after SystemCallError
use IO#pread if available in Ruby 2.5
*ZZZZZZ*
Please note the disclaimer:
yahns is extremely sensitive to fatal bugs in the apps it hosts. There
is no (and never will be) any built-in "watchdog"-type feature to kill
stuck processes/threads. Each yahns process may be handling thousands
of clients; unexpectedly killing the process will abort _all_ of those
connections. Lives may be lost!
yahns hackers are not responsible for your application/library bugs.
Use an application server which is tolerant of buggy applications
if you cannot be bothered to fix all your fatal bugs.

Current (tested r60757) ruby trunk warns in a few more places than
2.4.x did, so clean them up.
