REST API development has been settled down in V21.12.

Here are the critical points for v4.x and v5.x API users.

- v4.x Old XML/SOAP API is no longer supported in v5.6 and v21.12 and above.
- Some XML/SOAP methods are still usable using the following URL.  
  `/OpenLM.Server.Services/AdminAPI/web/{adminApiMethod}`
- Some of the v5.x REST APIs were changed in V21.12 and higher.
- Swagger API Lists are all the APIs for customer use and documents.
