Git tagging and rails gemfile

I have a gem that is hosted on github and not yet pushed to rubygems, and I added a tag to the master branch of the gem like this:

git tag –a v0.1.0 –m "gem version 0.1.0"
git push origin —tags

and then in a rails application I have on github I edited my gemfile like so:

gem 'your-gem', git: 'git://', tag: 'v0.1.0'

My question is, when I merge in additional changes into the master branch of my gem, my rails application will still point to the last commit before I made the tag? I just want to make sure adding additional changes to the gems master branch will not break anything in the rails app. Thank You
