I have some suggestions which I think are important to implement.
1. It looks like there's a lot of information being duplicated in the open
API file and the definitions.yaml.
2. A user needs to enter at least 6 fields to the definitions.yaml to
create a very basic API. This is a tad too much
The WSO2 API Manager team is pleased to announce the release of WSO2 API
Microgateway 3.0.0-Beta. It is now available to download.
