Gem update issue with ruby 2.2.2

Question

I was trying to update my ruby 1.9.3 to 2.2.2, and when i test in local that all was working fine, but when i try to push to heroku i got the raindrops issue version and then i update the rain drops by command

bundle update raindrops

but after that when i was checking this Gemfile.lock it shows

GEM
remote: https://rubygems.org/
specs:
  raindrops (0.17.0)
unicorn (4.6.3)
  kgio (~> 2.6)
  rack
  raindrops (~> 0.7)

Here the raindrops under the unicorn didn't change, the other one only changed, it push successfully, will it be make any issue for unicorn at any time in production?

Read you Gemfile.lock like this:

GEM
remote: https://rubygems.org/
specs:
  raindrops (0.17.0)     # <- This is the installed version (0.17.0 is the latest)
unicorn (4.6.3)
  kgio (~> 2.6)
  rack
  raindrops (~> 0.7)     # <- This is the version unicorn depends on

You have the latest version of that gem installed (see raindrops page on RubyGems). unicorn itself depends on a raindrops version between 0.7 and < 1.0, the version 0.17.0 fulfills this requirements.

All good!
