unicorn is an HTTP server for Rack applications designed to only serve
fast clients on low-latency, high-bandwidth connections and take
advantage of features in Unix/Unix-like kernels. Slow clients should
only be served by placing a reverse proxy capable of fully buffering
both the the request and response in between unicorn and slow clients.
Disclaimer:
Due to its ability to tolerate crashes and isolate clients, unicorn
is unfortunately known to prolong the existence of bugs in applications
and libraries which run on top of it.
Consider this just an announcement to inform existing users of a
new version, not something to convince you to switch to something
that set the entire Ruby world back decades in terms of concurrency.

Changes:
This release reduces CPU usage for Linux 4.5+ in most cases.
See "[PATCH 6/6] use EPOLLEXCLUSIVE on Linux 4.5+" for more details:
https://yhbt.net/unicorn-public/20211001030923.26705-7-bofh@yhbt.net/
There's a couple of updates for Ruby 3.1, but we've finally
started relying on Ruby 2.0.0 features after 9 years :P
(so Ruby 1.9.3 users are stuck with older versions).
And the usual round of doc updates and some build speedups.
13 changes by the Bozo Doofus maintainer since v6.0.0:
test_util: less excessive encoding tests
drop Ruby 1.9.3 support, require 2.0+ for now
drop unnecessary IO#close_on_exec=true assignment
extconf.rb: get rid of unnecessary checks
makefile: reduce unnecessary rebuilds
HACKING: drop outdated information about pandoc
http_server: get rid of Process.ppid check
worker_loop: get rid of select() avoidance hack
use EPOLLEXCLUSIVE on Linux 4.5+
allow Ruby to deduplicate remaining globals
epollexclusive: remove rb_gc_force_recycle call
drop Ruby version warning, fix speling errer
doc: v3 .onion updates, nntp => nntps, minor wording changes

* [PATCH 1/6] extconf.rb: get rid of unnecessary checks

SIZEOF_*, *2NUM and NUM2* should all be defined by ruby.h and
dependencies it pulls in since Ruby 2.0 and possibly earlier.
INT_MAX and LLONG_MAX are in limits.h which is POSIX.
HAVE_GMTIME_R is already defined by ruby/config.h, so we
shouldn't have to check for it, either.
Combined, these changes speed up extconf.rb by several seconds.

1-5 are straightforward changes, with 4+5 are probably
being long overdue.
PATCH 6/6 is fairly significant (more detail in that message),
but doesn't benefit completely saturated instances, either.
I don't know if completely saturated instances are that common,
actually...
Yup, unicorn using epoll: WTF :P
