Extensions¶

Extensions are a deprecated concept in Nova. Support for extensions will be removed in a future release. In order to keep backwards-compatibility with legacy V2 API users, the extension_info API will remain as part of the Compute API. However, API extensions will not be supported anymore; there is only one standard API now. For the current V2.1 API, Microversions are the new mechanism for implementing API features and changes. For more detail about microversions, please refer to Microversions.
