Does a compatibility matrix of client/server exists?

After this question on SO I tried to answer my best I wonder if a compatibility matrix exist between the server and client versions ? What I know for sure: you get a 500 error trying to run a chef client 12.0.? against an open source chef-server 11.0.8 but I didn’t try much. chef-client 11.16.4 works against a chef-server 12.0.4. But that’s all I’m sure. If someone has a more extensive test matrix it may be useful to include it doc maybe ?
