raindrops is a real-time stats toolkit to show statistics for Rack HTTP
servers. It is designed for preforking servers such as unicorn, but
should support any Rack HTTP server on platforms supporting POSIX shared
memory. It may also be used as a generic scoreboard for sharing atomic
counters across multiple processes.

Changes:
raindrops 0.16.0 - minor fixes and workarounds
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

Since Ruby 2.2, frozen string literals are implied for Hash#[]
lookups. Constant lookups have inline caching since Ruby 1.9
(from YARV).
Ruby 1.8.7 will continue to be supported, but the code will
favor performance features of newer Rubies.
