 As a general rule, if it is tested in the Travis CI matrix, it is a supported version. The section below details any specific versions that are _not_ supported and why:
 
-- Chef 12 prior to Chef 12.0.2 is not supported due to the lack of a declared resource type. This was fixed in [Chef 12.0.2](https://github.com/chef/chef/blob/12.0.2/lib/chef/resource.rb#L422-428).

 Additionally, if you look at a cucumber feature and see a tag like `@not_chef_x_y_z`, that means that particular functionality is not supported on those versions of Chef.
