Stats for SO_REUSEPORT sockets are now handled properly.
Thanks to Dale Hamel for the patches.

Dale Hamel (2):
      Fix queue stats for sockets with SO_REUSEPORT
      Fix off by one error in test

Raindrops may now use file-backed mmap() rather than anonymous
memory.  Thanks to KJ Tsanaktsidis for the patch:

The documentation is also updated to note our mail archives are now
available via IMAP(S).

This release fixes compatibility with GC.compact on Ruby 3.x
when using ListenStats on Linux.  The listener stats
functionality is rarely used and does not affect most users
who just have raindrops installed for shared atomic counters.

This release fixes some warnings on newer Rubies.

We're no longer on bogomips.org since it's due
for expiry and I can't pay extortionists for a .org, so
s/bogomips.org/yhbt.net/ for now, and be prepared to move again
when extortionists move onto extorting the .net TLD.

      doc: switch homepage to dark216
      ext/raindrops/extconf: fix cflags reset on ancient CC
      fixes for newer rubies
      replace bogomips.org with yhbt.net

This release fixes Rack 2.x compatibility for the few users of
Raindrops::Middleware
<https://bogomips.org/raindrops/Raindrops/Middleware.html>.
Thanks to Dmytro Shteflyuk for this release.

No need to upgrade unless you use Raindrops::Middleware with
Rack 2.x.

There's also a few minor, inconsequential cleanups.

Dmytro Shteflyuk (1):
      Properly override respond_to? in Raindrops::Middleware::Proxy

Eric Wong (2):
      Ruby thread compatibility updates
      tcp_info: remove unnecessary extconf.h include

The most notable feature of this release is the addition of
FreeBSD and OpenBSD TCP_INFO support.  This includes the
Raindrops::TCP for portably mapping TCP state names to
platform-dependent numeric values:

  https://bogomips.org/raindrops/Raindrops.html#TCP

Thanks to Jeremy Evans and Simon Eskildsen on the
unicorn-public@bogomips.org mailing list for inspiring
these changes to raindrops.

There's also a few internal cleanups, and documentation
improvements, including some fixes to the largely-forgotten
Raindrops::Aggreage::PMQ class:

This release features minor updates to support rack 2.x
while maintaining support for rack 1.2 and later.
As a result, Ruby 1.8.6 compatibility is gone, but
Ruby 1.8.7 probably still works, for now.

There's also a minor warning fix, doc updates, and
the homepage now supports HTTPS (HTTP remains supported)

5 changes since raindrops 0.16.0:
      drop Rack::Utils.bytesize dependency
      gemspec: bump Rack dependency
      linux_inet_diag: GCC attribute format check
      use HTTPS and move homepage to https://bogomips.org/raindrops/
      examples: add yahns config, zbatery is abandoned

There's mainly a fix/workaround for Ruby 2.3 now returning
locale-aware strings for File.readlink and our test suite
using strange paths allowed by *nix.

    https://bugs.ruby-lang.org/issues/12034

tcp_listener_stats won't return "true" object placeholders
if stats are configured for a non-existent listener.

There are also minor optimizations for Ruby 2.2+ (at the expense
of 2.1 and earlier).

And the usual round of minor tweaks and doc updates.

10 changes since v0.15.0:
      gemspec: avoid circular dependency on unicorn
      remove optimizations which made sense for older rubies
      linux: workaround Ruby 2.3 change
      linux: remove Pathname stdlib dependency
      add .gitattributes for Ruby method detection
      middleware: minor bytecode size reduction
      doc: update URLs and references
      README: remove indentation from URLs in RDoc
      linux: tcp_listener_stats drops "true" placeholders
      build: use '--local' domain for dev gem install

Thanks to Doug Forster for sending us the report.
