 AutoRest 3.0 finally supports OpenAPI3 files as an input format, with the following caveats:
 
-- existing AutoRest v2 generators may not support all features from OpenAPI3. (see next section)
 - `anyOf`, `oneOf` are not currently supported
 - other OpenAPI3 specific features may not be entirely supported.

 A new set of language generator plugins are being written that adopt the lighter-weight patterns for Azure Core libraries.<br>
-Existing V2 generators will default to processing with the AutoRest 2 pipeline. <br>
