ETA on new rubygems release with changes from #13

[silasjmatson]

I have a sidekiq.yml file with the following:

# Configuration file for Sidekiq.
# Options here can still be overridden by cmd line args.
# Place this file at config/sidekiq.yml and Sidekiq will
# pick it up automatically.
---
:verbose: false
:concurrency: 5

# Set timeout to 8 on Heroku, longer if you manage your own systems.
:timeout: 8

# Sidekiq will run this file through ERB when reading it so you can
# even put in dynamic logic, like a host-specific queue.
# http://www.mikeperham.com/2013/11/13/advanced-sidekiq-host-specific-queues/
:queues:
  - default
  - mailers

However, the concurrency option is overridden due to this line in the latest version available on rubygems: https://github.com/uken/guard-sidekiq/blob/v0.1.0/lib/guard/sidekiq.rb#L24

It looks like the issue was fixed in #13 but no new gem version has been released.

I can point my Gemfile to github for the time being, so it's not a huge deal.

Could we get an ETA on a new rubygems release with those changes?
