Version 0.8.0

• it moves the internal testing app into .internal_test_app instead of spec/internal. The Rails plugin gemspec includes all of spec in the gem, and we want to avoid including the internal application in any packaged gem.
• provides better error messages about resolving conflicts between your engine gem’s Gemfile and the testing app Gemfile
• provides engine_cart:server and engine_cart:console rake tasks to run the test app rails server from your engine gem project’s top level directory.
• warns about using out-of-date engine_cart initialization in your Gemfile
• tries to be more careful about using a clean testing environment
• runs bundle install with —quiet option (but rails generators will still run bundler noisily)

Upgrade guide:

• Update any spec/test_app_templates that use source_root paths that are relative to the test application to account for the change in the test app location
• Remove the spec/internal directory
• Add .internal_test_app to .gitignore (and, possibly, removespec/internal`)
• Update the engine_cart initialization in the Gemfile to have this:

# BEGIN ENGINE_CART BLOCK
# engine_cart: 0.8.0
# engine_cart stanza: 0.8.0
# the below comes from engine_cart, a gem used to test this Rails engine gem in the context of a Rails app.
