 ### Using other Rails-focused libraries
 
-Be aware that other gems may require parts of Rails when they're loaded, and this could cause some issues with Combustion's own setup. You may need to manage the loading yourself by setting `:require` to false in your Gemfile for the gem in question, and then requiring it manually in your spec_helper. View [issue #33](https://github.com/pat/combustion/issues/33) for an example with FactoryGirl.

 ### Environment and Logging
 
 Your tests will execute within the test environment for the internal Rails app - and so logs are available at `spec/internal/log/test.log`. You should probably create that log directory so Rails doesn't complain.

 ## Compatibility
 
-The current test matrix covers MRI 2.2 to 2.6, and Rails 3.1 to 6.0. It will possibly work on older versions and other Ruby implementations as well.
+The current test matrix covers MRI 2.4 to 3.1, and Rails 3.1 to 7.0. It will possibly work on older versions and other Ruby implementations as well.
 
 You can also use Combustion with multiple versions of Rails to test compatibility across them. [Appraisal](https://github.com/thoughtbot/appraisal) is a gem that can help with this, and a good starting reference is the [Thinking Sphinx](https://github.com/pat/thinking-sphinx) test suite, which runs against [multiple versions](https://github.com/pat/thinking-sphinx/blob/master/Appraisals) of Rails.
