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 0.17.0 - rack 2.x updates
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/

Since zbatery is abandoned, point users towards yahns
instead since that is what I currently use.
