 Bugs Fixed
 **********
 
+- **Commands:** Fixed a bug where generator commands did not sort the imports of a template with CRLF line endings.
 - **Security:** Fixed a bug where a valid JSON request body that is not an object
   (for example a JSON array) was corrupted after CSRF verification when the
   token was sent via the ``X-CSRF-TOKEN`` header.
