Latest Patch 0.6.4


Latest Release 0.6.0


  • Puma hanging in clustered mode. Breakfast would fail to cleanly exit on Puma exit, causing the server to hang indefinitely.
  • Bumped Rails version dependency, can be used with Rails 5.0 and greater. (Allows usage with Rails 5.1)


  • Capistrano rake tasks. Previous behavior has been included into the Rails asset:precompile task. Using the standard Capistrano Rails gem is all that required now.
  • Need for a custom Heroku buildpack.


Upgrading to 0.6.0 from 0.5.x

  • Update gem with bundle update breakfast
  • Update the JS package with yarn upgrade breakfast-rails
  • If deploying with Capistrano, remove require "breakfast/capistrano" from your Capfile. Remove any custom Breakfast settings from config/deploy.rb. Ensure that you are using Capistrano Rails and have require 'capistrano/rails' or require 'capistrano/rails/assets' in your Capfile.
  • If deploying with Heroku, run the following commands:
    1. heroku buildpacks:clear
    2. heroku buildpacks:set heroku/nodejs --index 1
    3. heroku buildpacks:set heroku/ruby --index 2

Note If you are deploying with Capistrano then Yarn is expected to be installed on the hosts your are deploying to.
