+Experimental features can only be used by enabling the `--experimental` configuration option.
 
 An experimental feature indicates to users that these features may
 change significantly in a future release and should be used only for
 testing, not (yet) for production usage.
 
 Currently enabled experimental features include:
 
-- support for easyconfig files in YAML syntax (see
-    [Writing easyconfig files in YAML syntax][easyconfig_yeb_format])
-- support for generating container recipes & images (see
+- support for generating container recipes & images (see

-- support for using easystack files (see

 - support for trying to update versions of the dependencies of an
     easyconfig based on what is available in the robot path (see
     [Output of `eb --help`][basic_usage_help])
-- support for installing extensions in parallel (see
