## New features and enhancements

- **OAuth 2.0 - Reusing refresh tokens**   
  Apigee Edge now provides an option ([ReuseRefreshToken](https://docs.apigee.com/api-platform/reference/policies/oauthv2-policy#reuserefreshtoken)) to enable OAuth 2.0 refresh tokens to be reused, rather than having new refresh tokens created when a refresh_token grant request is issued.
